Please see screenshot attached...I cannot get Smart Sync to work anymore in MacOS Big Sur (reproduced on Beta 5, 6, and 7). I'm currently running Dropbox version 105.4.651. Is there a new Dropbox beta version that fixes Smart Sync?
I am having exactly the same problems. Smart Sync not working. Constantly displays message "Smart Sync is experiencing an issue…" Tried deleting Dropbox and reinstalling. Tried 'solution' referred to in post above. Problem persists. Cannot change files from local to online storage. Online chat could not solve the problem.
