Oauth login in MS Teams 3rd party app is showing white login screen for some users on desktop
Microsoftandrew1992 - The fix was in internal ring. We are checking the status with engineering team if the fix has been rolled out publicly or not. We will inform once we get further update. Thanks!

andrew1992 - Thanks for informing. Appreciate it.
Prasad_Das-MSFT I have a note to reach out. For many of our accounts that were experiencing this, the issue has been resolved (including my own that we were testing this issue out on).
We did receive 1 mention of this lately; however, it seems that there has been a big improvement. Thank you!

Karma_bot thanks for letting me know. We also continue to experience it with similar frequency of customer requests.
@ChetanSharma-msft for your knowledge, recently a change was made so our "Pop out tab" workaround no longer works. Potentially this is part of figuring out how to debug and fix the issue; however, now we have no workaround for our users who run into this.Is there anything else we can do?
andrew1992 @ChetanSharma-msft Issue persists, affects a lot of clients and wasn't resolved. It has been ongoing for at least two years now and affects thousands of users, and I cant understand why Microsoft cant fix it. We have clients email us every week with this issue and I can't help them.
- ChetanSharma-msft unfortunately the issue still persists.
My Teams desktop version: "You have Microsoft Teams Version 1.5.00.21668 (64-bit). It was last updated on 2022-08-18."
Happy to set up a call to help debug.
On Teams desktop, if I click Pop Out Tab -> the login still works. And if I refresh the tab afterwards, it then appears as it should within the frame. 
ChetanSharma-msftHello Karma_bot, andrew1992 - We are not able to repro this issue.
Can you please try updating your Teams Desktop client once again and please confirm if you still face this issue?- Karma_bot did this work for you?
Prasad_Das-MSFT On our side, I am still receiving the white login screen and completed the following:
MSFT Desktop Testing:
- updated Teams version
- cleared app data C:\Users\MYUSER\AppData\Roaming\Microsoft\Teams
- uninstalled / reinstalled Teams
- uninstalled / reinstalled application receiving white screen
- tried developer preview
If I click "Pop out tab" and login, it still works. However regular happy path flow does not - Prasad_Das-MSFT
Karma_bot - We got update from engineering team that it is fixed and rolled out publicly. Please update your MS Teams version and check if it helps. Thanks!
@Prasad_Das-MSFTandrew1992, our product is affected as well. Hundreds of users, if not thousands, have been impacted in the last year. Any ETA on that fix in the production environment?
