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

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.

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

    Thanks a lot for all this information - it works for me, too - just wanted to share the following interesting insights:

    When you start the session (in full-screen-mode - because it won't work otherwise - see above) you can then

    a) switch between desktops and everything works fine!

    b) you can even go back to the window-mode of MS Teams...

    You only need to have teams in the full-screen mode to START the screen-sharing session....at least, so it seems...

    Very interesting bug...

    Thanks Deblanko.

    For me it´s the "drumroll" Microsoft ToDo-app... :D

    Yes, same for me. Closing Microsoft To Do solved the problem.

    I found the culprit on mine.  The To Do app from Microsoft can't be open when I try to share my screen.  I close it, and I can share my screen.  As soon as I have To Do running, it won't work.

    I don't have To Do and I still have the same issue. Expand teams to full screen and it works. Windowed and it does not.

    Thanks Deblanko for the idea. I worked through my open apps one at a time until sharing started working. In my case it was the Sonos app. It seems that they don't have a version that plays completely nicely with Catalina. If I don't have that app running, I can share everything in teams like pre-Catalina. Woot!!
