I published an update to an app built in Dataverse yesterday and it wouldn't load. I backed out my changes using a restore and it started working again. As the change was necessary, I worked on it again but every time I published the app, it wouldn't load. I finally noticed that the Power Apps release version had changed to 3.21031.49 when I published it yesterday. The working version of my app is 3.21031.41. Is it possible to change which Power Apps release is used when publishing? I can't find an option in the settings for this, but I have a rather critical change I need to make in an app that won't work with 3.21031.49.
Go into the File-> Account part of your app and you will see a "Change authoring version". You can try to change it there.
I hope this is helpful for you.
Ah, yes...not sure how to change that version then for Teams.
If there is a breaking issue then, I would suggest placing a support ticket with Microsoft on it.
