I updated to MacOS Catalina and now I cannot share my app screens. I can share my desktop, but that is all others can see.

Found it.

System Preferences

Security & Privacy

Privacy

Screen Recording

My system had an entry (unchecked) for Microsoft teams. I think it asked me as I was launching but I blew by it. Not sure how you'd add it if it's not there. You just have to turn it on, and Teams screen sharing will work.

    I have Catalina as well and this WAS working yesterday. This morning, Teams was updated to 1.2.00.28258 and now I can no longer share my screen. It could also be related to the MacOS update that happened yesterday. The preference box is checked in the panel; I have checked and un-checked it, rebooted, etc. and still Teams is sure that it does not have permissions to share.

    After being bugged with this for a while and trying the full screen workaround it suddenly dawned on me that it was caused by the enumeration of the activate apps and one of them was causing the privacy issue.

    It turned out that the the Cisco Any Connect (VPN software) was the culprit.

    Without it running everything was fine:

    • Reboot would work until you launched the naughty app
    • Full screen would work because it only offers Teams and full screen to share

    It fails when Cisco Any Connect is running and Teams tries to ask it for permission to share.

    Therefore I guess the issue is with another 3rd party app not compliing to the access request, in my case the VPN software...

    same session - just go to full screen and it works, go back to windowed mode and it stops working...

    When I tried it with full-screen mode of Mac OS, it works... I don't know why but it works fine so far.

    OK - clarification, it's now working.

    After I installed Catalina, I attempted to do a direct screen share with a colleague (using the Up Arrow in the Box icon).  That is what gave me the message about needing permissions, but when I got there, there were no entries for Teams to select.

    I went to the Calendar link 

    and clicked Meet Now

    When I did that, I received a different Pop Up (a Mac pop-up) asking me to grant permission to add Teams to Screen Recording.  Now I have Teams under Screen Recording and am able to properly share my screen!  I know others have indicated it works temporarily for them - my original problem was getting Teams to appear under Screen Recording.  It appears starting a "Meeting" vs a simple screen share request is what triggered MacOS to prompt/add MS Teams to the list.
