Screen sharing not working under OSX Big Sur
Since upgrading to Big Sur the screen sharing feature does not work anymore. All permissions granted, however selecting any of the sharing options (selecting the screen to share) does not have any effect -> the options don't disappear after the selection and the sharing is not started.
Update: I've now started a meeting with only myself participating and was able to activate screen sharing (of course without seeing whether something would be shown for other participants). I'll check in the next meeting, whether the problem returns.
On first attempt to share my screen the Teams client opened up something inside the new Big Sur System Preferences; but without any guidance about what to do next.
Subsequent attempts to open the "share tray" in the Teams client resulted in a big black box at the bottom of the screen....
Same issue here since updating to Big Sur. I can't even screen share in a meeting alone, much less with my students. It just keeps spinning and spinning.
