The latest Zwift update has been announced and will be released in phases over the next couple of days. This is a minor update mostly focused on fixing issues introduced in the previous update (1.39.0). Let’s dig into the details…
First, A Note from Zwift
The forum thread for this update begins with this post from Mike Lusthaus, recently-hired CTO at Zwift:
Hi everyone,
I’d like to take a moment to introduce myself. My name is Mike and I’m the Chief Technical Officer at Zwift. Our last game release, version 1.39, was not at the quality level that it needed to be, and we know that there were many issues that prevented you from enjoying riding and running in Zwift. We take your feedback very seriously, and are grateful to the many members of the Zwift community who reported issues and provided helpful information about your experience, environments, and devices.
The new game version 1.40 is focused on resolving many of these issues as our top priority, and we have many additional fixes and improvements actively in development which will be released as part of our next game release real soon.
Version 1.39 is an important release for us as it contained a major merge to our game codebase. We tested it a lot and rode it internally for weeks but still missed some things we should have caught. Going forward, we won’t have this type of merge behavior and while we will still introduce issues from time to time, they shouldn’t be as broad as the ones we introduced in 1.39. As you’ve likely noticed, we’ve been investing in our game launcher so that we can release phased rollouts of new versions (which lets us minimize blast radius in the event of an unexpected critical issue), and we’re investing in our automated testing and crash detection systems. We have a renewed focus on driving down existing bugs and quality-of-life issues in the game, and we’re in the final stages of testing Zwift for native Apple Silicon which we’ve observed to have huge performance improvements across the board.
Thank you for your patience and please keep your feedback coming. We’re working hard to keep you riding and continue to improve the experience alongside launching new features.
Mike Lusthaus and the Zwift engineering team
A few worthy callouts from Mike’s note:
- An exceptional update: Mike notes that 1.39 “contained a major merge to our game codebase” but also notes “Going forward, we won’t have this type of merge behavior”. Sounds like Zwift is planning to make code changes in smaller but steadier steps.
- Investing in testing: Mike says “we’re investing in our automated testing and crash detection systems.” Applause for this! We would love to see Zwift provide more detail as to the cause of crashes, and of course better automated testing is a big win for everyone.
- Zwift for native Apple Silicon coming soon: “we’re in the final stages of testing Zwift for native Apple Silicon which we’ve observed to have huge performance improvements across the board.” This should be very good news to everyone with a newer Apple machine that uses Apple silicon.
New Look for Ride RoboPacers
RoboPacer cyclists have been modified to look like actual robots instead of holographic humans:

One reason Zwift told us this change was made was to make it clear that RoboPacers put out a draft “shadow” just like any other rider. Making them look like actual physical riders in game, and not a hologram, helps clarify this while the robo look makes it clear they are automated riders.
Run RoboPacers have the same look as before, but Zwift says this will change in a future release.
HoloyReplay Icon Tweak
The beacon floating above the head of HoloReplays has been modified so it’s different from the RoboPacer beacon (see below). This icon was also updated in the rider list on the right.


More Fixes and Tweaks
Here is the list of fixes/tweaks Zwift included in their release notes:
- Adjusted estimated duration for La Reine to bring it in line with other routes.
- Joining a RoboPacer or another Zwifter is more reliable.
- Fixed an issue causing misrouting when riding the Big Foot Hills, Downtown Titans, Zwift Gran Fondo 2022 or Eastern Eight routes.
- Fixed a crash during launch when running on Windows N Edition.
- Fixed a crash on Android when signing in for the second time after saving or discarding a ride.
- Fixed a crash that could occur when scrolling through race results.
- Fixed an issue preventing calibration of the Sterzo steering device.
- Fixed an issue with the Zwift Hub not properly setting “free ride” blocks from ERG mode to SIM mode in workouts.
- Fixed an issue that was causing the Zwifters Nearby list to scroll unexpectedly while viewing other Zwifters and made the Ride On button inaccessible.
- Fixed an issue where Kickr Bike steering could not be disabled.
- Fixed an issue with Tacx trainers not properly applying correct road feel for tarmac and cobbles.
- Fixed an issue where additional cobblestone sections were appearing in France.
- Fixed issue where running kit changed colors mid-session.
- Fixed an issue where some effects like dust and rain were glowing.
- Fixed an issue where menu buttons would be unresponsive if the Action Bar was visible.
- Fixed the interaction for ignoring screenshots when ending an activity.
- Fixed an issue where some Notable Moment screenshots were blurry.

- Difficulty editing intervals in workout editor due to remapping of arrow key behavior
Questions or Comments?
If you spotted any other changes or bugs in the update, please comment below!
I’d like to know when they will be fixing the glitch when you know damn well you are pedaling, or someone else is pedaling because you can see their w/kg but the Avatar’s legs don’t move. That is the most annoying thing.
No cadence sensor – used to happen to me, no sensor, no leg movement on avatar
Actually, you should only see the “no pedaling” behavior if you’ve paired a cadence sensor, but that sensor is reading 0.
If you don’t pair a sensor, your avatar will pedal at a steady pace. Zwift set it up this way so you don’t have a bunch of non-pedalers flitting about!
That said – there are occasional bugs where the game is showing your cadence numbers correctly, but your avatar isn’t pedaling. I haven’t figured out what causes that yet, but sometimes changing camera views seems to fix it.
Thanks Eric, I’ll try that if it happens again.
Another way to fix it which has always worked for me is to do a very brief high power sprint, literally just a couple of seconds so it registers. Not sure why it works but it has always
Adding to this discussion: there’s a known issue with some smart trainers where they will *read* zero cadence if your pedal stroke is *extremely* consistent.
Some people solve it by pairing an external cadence sensor from a pedal or crank arm. (not always practical if you don’t have one of those or are on ATV and run out of available sensor slots)
A quick sprint also fixed it
Just posted that then saw this, must read thread fully, lol
I can regularly get mine to stop pedalling at certain points on courses. ie Tick Tock after the desert and the turn off for Titans Grove. The descent down towards the ocean tunnels my avatar will stop. There’s a few other places that it regularly occurs on.
if you haven’t already put a ticket in to Zwift tech support then you should. You have pin point areas where the issue can be recreated.
I raised a ticket for that spot a long time ago. I got crickets as a reply.
I’ve had this problem for the last couple of weeks. I’m using the Elite Suito T and my cadence sensor is connected and shows the figure in the corner of the screen when riding, but my avatar is not pedalling. Strangely, this only occurs when riding with a PP in Watopia. I’ll try your tip of changing camera views, thanks.
I was puzzled as to why my rowing now leads to a pedaling avatar – this now makes sense.
I had the cadence sensor connected. I checked the pairing page. It’s not the end of the world but just annoying, like a mosquito.
I’ve only seen this when joining a robot ride. Nothing to do with cadence sensor- I ride a Wahoo Kickr Bike and it comes with the territory.
same, and it will always resolve itself…. i will try the sprint idea above… love zwift
It happens with me and my Kickr bike too. Not too annoying.
I have a cadence sensor. This has happened to me.
have that one today with the new version. And i have cadence sensor and it was counting
I have the neo 2t which includes cadance and when i ended a workout and start a robo pacer session afterwards my avatar dont pedal for about 5 min , after a little time all is correct.
It’s not about the cadence sensor. Whenever I join a pace partner, my avatar is not pedaling for some time, but I see the numbers for cadence on screen.
I believe this was a new bug since v. 1.39 and has been reported many places in the zwift forums. Legs weren’t spinning regardless of the measured cadence.
I got the impression that this bug had something to do with the coffee stop feature (I assume the legs aren’t supposed to spin when you’re having that sip of coffee, at least those with a coffee cup above their head weren’t spinning either). When I tried v.1.40 a couple of days ago, it looked like the bug had been resolved, though!
Still hoping for them to fix the garage so that it opens on the bike setup we’re currently using (the way it used to) rather than opening on the top bike on the list.
I just tried it out and could not open the frames section to change frames. Sadly I recently purchased a new frame and wanted to start using it, but no joy.
“The beacon floating above the head of HoloReplays” – I think you mean RoboPacers there
Fixed!
@Eric Schlange I’m guessing the text in your HoloReplay Icon Tweak section shouldn’t refer to HoloReplay twice but once to HoloReplay and once to RoboPacers?
Fixed!
When will android users be able to upload videos to strava etc, while riding in zwift? It has been a while now since only 🍎 users were able to upload videos.
Zwift hasn’t given any dates. Far as I know, it’s only live on iOS at this time. Not available on AppleTV, Mac, PC, or Android.
“The latest Zwift update has been announced and will be released in phases over the next couple of days. This is a minor update mostly focused on fixing issues introduced in the previous update.”
^^Just keep this as a cut and paste for future articles.
I just joined a group-ride at leithhill after party. The ride ended at 60 minutes. I kept riding to test the coffee break on a climb. Using the button gave me the 100kph badge during the climb
That sounds like a bug I want.
I had that as well. As soon as I stepped off the bike, it accelerated to 100mph (not Km), then slowed again by the time I got back. Didn’t realise till the video!
I have problem giving thump up to otjer riders. When the sign occur next to a riders name i press it but the list is scrolling down and the sign has a white frame around it. Took me four times before it worked. Never been like this before.
Do you have the new version (1.40) installed? It’s supposed to fix this issue.
Is there still the issue where after a coffee stop, the controllable functions on the kickr bike stop working? (Steering, powerups, u-turn buttons). They work before a coffee stop but not when you resume the ride.
Not sure – first I’ve heard of that. Have you reported it to Zwift?
Known bug with coffee stop and kickr bike steering failure. . Several people claim to have reported it. Doesn’t show on the big fix list 😕
I’ve been wanting to try a coffee break, but (even though I don’t use a Kickr Bike) I’ve been afraid of this happening and my computer takes long enough to restart that I haven’t bothered yet.
This only applies to Apple Silicon running macOS, right? iPads have always run Apple Silicon, but the app seems to be locked at 30fps with only Basic assets available. It massively limits performance, considering they run the same M2 as the Macs.
I believe Zwift’s support for Apple silicon will eventually apply to all devices using Apple Silicon (ARM64 processors). So basically all the newish iPhones, iPads, and Macs (I think).
Zwift tells me iPads and iPhone will see a performance boost eventually, but Zwift is prioritizing MacOS devices first.
Great, hope they reach parity soon!
To be clear on my point, Zwift has always natively supported Apple Silicon on iPhone and iPad – they’ve only ever been Apple Silicon. I just hope the assets and capabilities of the macOS version (4k, Ultra, 60+fps) now make their way to mobile, considering iPads run Mac processors.
The huge increases in power over the last 7 years, being left on the table. Frustrating to see!
Zwift’s code doesn’t run natively on Apple silicon (like iPhones) currently. A translator is used to convert Zwift’s x86 code into Apple’s ARM64 code.
Running the code natively removes the translation step, and (I assume) just makes it easier to take advantage of the power of Apple silicon. Hence the performance boosts Zwift is seeing in testing.
@Eric Schlange, iPhones (and other mobile devices by Apple) don’t even have Rosetta: they’ve used ARM from the start, so there’s never been a need for a x86 compatibility layer. Zwift on the iPhone uses ARM code natively. (and so does Zwift on Android)
What about updated visuals as well as performance? Zwift already runs great on my M1 Macbook Air (60fps most of the time) but lacks stuff like the detailed shadows etc that you get on the PC.
Did they fix the runpod connection, people on Reddit were having problems connecting after the update. We have to go into ride and then run for it to appear.
Ooh, that is a good fix that I hadn’t heard of. Will have to try it (assuming they haven’t fixed it). Thanks.
I appreciate that they are owning up and going wide with the messaging that they get it. This is an encouraging sign.
I noticed a few of the bugs …just reloaded and they resolved. Keep up the good work thanks for the update (I can’t believe some people are so inflammed with such minor issues)
“Vertical scrollbars not functioning properly in the garage when trying to scroll through items using your mouse in Windows 10″
Also on MacOS using trackpad
Hey look they fixed the Downtown Titans bug I reported! At least I don’t feel like I’m crazy anymore. For about two weeks everyone responded like I was licking toads or something. 😉
I don’t know how to suggest it but having a customer service function that allows people in CS who have confirmed when people complete particularly long routes and have routing bugs happen that they can be awarded the XP and drops. While researching my issue I came across so many heart-breaking stories of lost hours, somethings 5-10 hours at a time (one on the longest route possible), and no credit because of a verified Zwift bug. It would really go a long way toward acting on the good faith they want to build supporting and reporting these bugs if the… Read more »
Are there plans for a customizable HUD/GUI? It would be nice to reshape, make transparent, and move the metrics widgets; especially for streamers.
sauce for now it seems
Any word on Zwift optimisation for Apple TV 3rd gen?
When I ride any of the London routes, my elevation count (mine is in feet) doesn’t work properly. When riding uphill, on all other worlds, the elevation count goes up by 1 foot at a time (quicker increase on steeper hills), whereas in London routes, this stalls and usually goes up every 7 feet. However, by the end of the route, it is usually missing around 200 feet of climbing in the elevation count, based on the advised route stats. Does anyone else have this issue and know when this will be fixed? Thanks.
The new Robo-pace partners are absolutely ridiculous. A cross between Robo-cop and a roasted chicken. I hope Zwift is monitoring the in-game commentary on these new bots. I wish Zwift would spend their time and resources fixing issues/bugs – testing before releasing updates and improving the customer experience. It’s almost as bad as the unlock awards from 50-60 – complete nonsense.
“I wish Zwift would spend their time and resources fixing issues/bugs – testing before releasing updates and improving the customer experience”
They could spend ALL their developers’ time doing that, and some would still sneak through and nothing else would ever get done.
It is possible to do more than one thing at the same time when you have a team to work with.
Also, I like the new look RPs, so …
Very much don’t like the new robo partners. They are creepy.
I love Zwift, but really they seem focused on fixing bugs and finding solutions at “problems” that nobody cares about (the look of the robocops?! Really?). Unless I have missed it, when can we have, for instance, a decluttering function for the garage, or a no-stop bike swap?
They removed the no-stop bike swap on purpose.
I tried to take screenshots riding with the new pacer in drone view ( type 0 on PC) and it was not working. Did not try riding otherwise.
Bug in Zwift running. When selecting custom goal distance, like 7.5km, it will still end up as 40 something km and when trying again the distance just gets longer and longer. Other custom targets as time in zones, cal, etc seems to work
Already have that version and i had a problem starting with the robot pacer in Watopia.
First my avatar legs were not moving. Them when i rejoin there was nobody there no even the robot. try again same problem.
Moved to Makuri and no problem
After this update. I couldn’t use my apple remote to activate any power ups. I had to resort to the companion app.
My only additional request is for less resistance baked into pedaling while looking through the menu screens. My Z Hub seems to be in ERG mode when I login, and the resistance is a bit much for cold knees & ligaments.
Just finished a ride in Tick Tock, and there is a new road in the map, paralell to Titians Grove, but clore to the sea. Do we have new roads in Watopia coming soon?
I’ve seen it there for a little over a week now. I was wondering the same thing.
Came here to ask about this. The portal was supposed to be at the volcano so this might be a connector that skips the titans Grove?
And not a single new bike since I don’t remember when…
Anybody else finding the new pace partners harder to spot in the pack? I almost got dropped a time or two when it moved to the front.
Hi all – anyone has any issues with being passed by cyclist cycling at much lower w/kg? I joined one of the RoboPacers (1.8kg/w) on what was supposed to be an easy recovery ride but had to go to 2.4kg/w to keep up…
On a flat course the actual wattage is more important than the w/kg If you are lighter than the pacer, you will need to put out a higher w/kg to hit the same number of watts.
Did you check what bike you were on?
Copy/paste on Windows 10 issue not resolved.
As Zwift improves the robo pacers, it would be really nice to be able to jump to/find a different pacer in the same world without having to end the ride. For example, I might warm up for 15 minutes at a lower pace but then desire to jump to a higher w/kg pace or even the next level, say D to C. I know we’d have to stay in the same world, but how great would it be to be able to move from one pacer to another!!
Yes, teleport is one of the features announced to come out this summer.
Will Zwift for Chromebook ever come to fruition?
Highly doubtful.
During an recent event I got rerouted and lost the group I was riding with. Rejoined the event and soon got rerouted for a second time. Then continued riding and was almost back in the group after a longer route, then for the third time got rerouted during the event. I gave up, very irritating.
I’m using Windows 11 rather than 10, but was surprised the other week when I could not scroll through the frame/wheel options in the garage. I used the up/down arrow keys, but they would only scroll through what was visible on screen. However once I had used the arrow keys, I could now use my mouse to scroll down the complete list. Hope this useful for anyone struggling to change their frame or wheels.
Since the recent software update I’ve noticed the following.
Suggestions?

My Training Peaks daily workouts have dissapeared too!!
I seem to loose connection with my companion app. Sometimes it’s working while in the pen before a ride starts, but after starting I do not have access to it. I’ve tried rebooting, turning off cellular data etc, but most rides, I’m unable to type/chat and no ride-ons. Suggestions? Possible bug?? Thank you
Ride report – didn`t notice any message about this. Power graph – non existent. Scroll of participant list not working after any ride.
save screen at the end of a ride has several minor but frustrating irritations: buttons on save screen ride go bananas, randomly blinking and changing size, and start interfering with other operations… also finding the quintuple-clicks to select an image to upload is needlessly tedious. Lastly, the club drop-down that doesn’t remember what I set it to every other time and which automatically changes back to the club I just de-selected as I save is some dark-pattern stuff.
How hard can it be to NOT turn the pain effect back on after updating? It’s EVERY EFFIN’ TIME – and I hate it. Seriously, why is that [email protected]&” forces on me?
while riding the latest update, I periodically see black squares popping in the field where there should be other riders. Sometimes these obscure most of the display. I find it really distracting.
Known bug. Fix coming.
The visual quality of Zwift world’s for me is the appeal in riding virtually, the intention to use 3d modeling itself to replicate reality works for me. That is to say, modeling avatars to have very human qualities in the way their drawn anatomically correct is appealing (however I hate that female riders can look skinny and frail which is ridiculous because many woman who are athletes have very well developed muscles, looking at you Zwift to fix it!!!!!). Drawing the worlds to replicate the look and feel of the materials they represent like stone and water and landscaping is… Read more »
What was a non issue is now an issue again. Two updates ago, I noticed that my XP was not calculating correctly. Eric pointed out that although the in-game screen is showing 10 or 20 XP I was truly earning 2x that amount as I am currently level 56 making my way to level 58. I was okay with that because in the end, since I’m above level 50 I knew I’d ultimately get to my appropriate level. However, I’ve noticed I’m no longer earning 2x points. Anyone else noticing this? My progress bar still shows level 56=>58 yet I’m… Read more »

Will the bike shop updated in the feature?
Why did there come such black fields where there should be rear lights, that have come after the last update ?
Loving the new look Robo Pacers.
I hope zw side chat box can display East Asian characters properly, companion also had some obvious translation errors but never changed them, 4 example ‘minutes’ is translated as ‘meter’ in Chinese
Sad to have lost the ability to see who I completed a group ride with … it’s a great feature I use as a sweep to message riders post ride to congratulate them etc.
