I work for 4 different companies. Each one have Teams. I can't even put the 4 accounts in the desktop app. I can do in the mobile, but not in the desktop.

I had to install containers in firefox, and open 4 tabs to be able to use the 4 accounts at the same time. And of course, because Im using firefox, I can't use the camera in video calls because microsoft allows only chromium browsers to do so.

And the linux client is bug as hell.
