Several users not able to join or participate in Adobe Connect Meetings (especially Mac)

We use Adobe rooms about 30 times a day.  Users are regularly encountering a wide variety of problems since the forced update to 11.2.  There are too many to list, but Mac users seem to have the hardest time (myself included). 

On a two year old Macbook running OS 10.13 High Sierra, using the new app, I am booted from Connect whenever I try to turn on my mic or speakers or video.   If I join by HTML, it works for a while then audio disappears.  I can't screenshare in either the app (booted from the room) or HTML (not allowed in HTML).

( I have uninstalled flash player, I have installed the latest Adobe Connect app, and I have changed the security permissions to allow Adobe Connect to control my computer (SystemPreferences/Security&Privacy/Accesibility/Privacy)

On a 6 month old Macbook running 10.15.5 Catalina,  I can join via the app and use the mic, video, and speakers, but when I share my screen, only the desktop displays to the other users.  If I share an individual app, nothing displays, only a grey screen.

( I also have made all the updates listed above)
