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.

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.
As a work-around, have you tried sharing while Teams in in fullscreen? That worked for me for now. Green button, not alt-green button for fullscreen.
I tried that several times and it does not work.
interesting - that looks to work!!!!
A possible cause of the problem - please excuse the swearing, I think the poster is annoyed
