Hi. Also got stuck! Working fine on my imac (10.15 catalina) but no green or blue ticks on my new macbookpro. Did everything and eventually went as far as a clean OS install, fresh install of Adobe, everything new without any other software installed. (So just the OS and Adobe). Also did not install dropbox just in case that caused the problem. Did all the other stuff – uninstall/repair of Creative cloud, turning extentions on and off, signing out and in, stopping coresync / helper / desktop services in activity montor.
After no luck I installed Dropbox - working perfectly with sync icons.
It's really usefull to see what is syncing / what is not. I get the blue sync icon in the taskbar when syncing creative cloud files and all files are synced, so it's working, but not showing.
So I guess I can't move to Big Sur on my main work computer before this is fixed. So frustrating.
Yep, same issue here. No more green checkmarks, no more links etc. on right click. After connecting to adobe support I tried a lot of the stuff you told before. Even deleting CC Desktop App via cleaner tool. Unfortunatly no success at all. Indeed, very frustrating.
Don't know what else to try. Maybe someone can help finally. Would be amazing!
