screen share pausing

I came here to ask the same question. Since the new update, when I choose Advanced Screen Share my students only see a black screen. When I screen share with the full screen, which I don't like as it's unprofessional, the students now see a black square where the video feed is on my end, and a black rectangle for the toolbar. This obscures their view of the slides and worksheets. Any ideas on how to fix this or how to undo the latest update?

I have been in the same situation since yesterday; this is horrible.  I think I lost a potential client yesterday over it.  I looked unprofessional..  I can't get it to work.  Tried uninstalling and reinstalling.  It says to clear my Zoom cache and give permissions in an old post, but no description of where to find those two things specific to Zoom.
