App not working in MS Teams


suddenly my PowerApps application do not load anymore in MS Teams. Nothing changed in my application since weeks and the app have been working just fine. Since today all I get are the 4 dots during loading screen, but nothing happens after 1 hour.

App is loading and working fine in web browser and on mobile. Any ideas what can be wrong?

I've got the same issue, the app is not working in Teams. 

I've raised a support ticket to Microsoft about this and got the following reply: 


"There is an outage regarding the Power Apps integration with Teams and SharePoint and several users are impacted across all regions. Our product team is actively working on it and we are trying our best to fix this as soon as possible."


Let's hope they will fix it shortly.

FYI - To those following this thread, MS is aware and working on it. There's an incident report in the M365 Admin center:

*Update - for full closure this is the update of the fix implemented:

Maybe be some Upgration happens from Team/Or PowerApp Side.


Please try to re-install /register the app in Teams. 

Hope it will resolve this issue

I'm having the same issue. Was working perfectly last week, but today my Teams PowerApp loads but doesn't show any data, it's just in a loop trying to load it. However same with @Lubeno78 it works on Web and Mobile.

Hello, I too am experiencing this problem.  On Desktop, Mobile and Web.  On desktop, after around 5 minutes, I'm prompted to sign into PowerApps.

I see that when I stay on app screen in MS Teams for quite a long time, there's an "sign in" pop up (text: Sign in to start using PowerApps).

When I do, my application is back and I can work with it!

...until I leave app screen and choose something different, e.g. chat screen or screen of any group/channel. After that, I have to wait again for "sign in" pop up and sign myself to get it work 😞


@microsoft:  PLEASE HELP!!

Add another organization to the list where coming in this morning and most Power Apps within the Teams desktop app do not load. I'm guessing it is related to the user session not being signed-in or recognized as that happens sometimes with Outlook web pages that are set in tabs. The only way around it that I know of is for the user to clear their cache but it's absolutely ridiculous to expect all users to do this, let alone have the knowledge of doing it.


Microsoft.... this is yet another aspect that makes it very difficult for us to encourage adoption on your products...


Hoping there's some response on this most current thread that has a solution that can be pushed out to fix for the users. All other older threads I've found on this don't have any real solution either.



can you tell me what steps exactly to perform to "clear the cache" --> I'd like to try.
