I think it sort of worked on firefox for a spell a while back but screen sharing and other stuff was broken. Then I think it stopped entirely and showed a "use edge" callout.

I switched to the electron client they provided and it used to work pretty ok for years but recently they anounced they were killing it on linux for some reason (to be fair there were no updates I could discern for months).

They now ignore linux entirely in the desktop clients section and redirect to a qr code to download the android app if you go to a download page on a linux machine.

I have chromium just to be able to get on a call if needed.

There is now "Teams Classic" and "New Teams" as well.

All this to say, yes. MS enshitification is real. Sorry I know you did not sign up to get this wall of text.
