Hello ceo optimus prime,
Good day!
Thank you for bringing this issue to our attention.
It's possible that there may be a compatibility issue with the desktop app and the way it handles cookies. To troubleshoot this issue, I recommend trying the following steps:
Clear the cache and cookies in the desktop app and try accessing the URL again to see if all cookies are being set. Here is article regarding: Clear Teams cache - Microsoft Teams | Microsoft Learn.
For New Teams:
C:\Users\%username%\AppData\Local\Packages\MSTeams_8wekyb3d8bbwe
For Classic Teams:
%appdata%\Microsoft\Teams
Adjusted instructions that cover both app types.
If Teams is still running, right-click the Teams icon in the taskbar, and then select Quit.
Open the Run dialog box by pressing the Windows logo key + R.
In the Run dialog box, copy/paste:
Delete all files and folders in the directory.
Restart Teams.
If the issue still persists after trying these steps, please provide us with more details such as the version of the desktop app you are using and any error messages you may be receiving. We will do our best to assist you further.
