I am on a Mac and my screen sharing always worked fine but this week it won't show my screen on my end when I screen share, the other users can see it fine but I can't see it and I need to be able to see it. When I click away and get the little floating screen it actually shows up but I need it in the full view and have tried every trouble shooting trick on google, it must be the new version of teams, i have tried the web browser it doesn't work, I have deleted the cache, I have made sure screen recording is enabled, I have shut everything down multiple times and started again and just don't know what else to do.

Also, it appears that you are the only member of this meeting. Check what happens when more users join this meeting.
