The dropdown context menu (right-click on Mac) isn't showing

Hello, just circling back as this has been solved.
SOLUTION: Quit DropBox, delete any/all DB folders in Finder, restart DB, and relink when prompted. Dropdown Context should work fairly immediately, but wait 24 hours or more for status icons.
STORY: This problem existed on both my M1 Desktop and my M1 MacBookPro. Back in June, I did jump out of this forum to contact DB support directly, as Jay suggested. At which point, after many other attempts,  they suggested I make a "test" user account just to see if the problem existed there. It didn't, which pointed to it being an Apple/OS/extensions issue more than a DB issue.  However, the next day I booted up with my normal user, and suddenly the context menu was back.  No status icons, but after a few days those were showing up.
But the issue still persisted on my MacBookPro, even after updating to Sequoia, and after trying the same fix/workaround that worked on my desktop. After months of not having the functionality, I had a bit of time to troubleshoot more late September.  I burned through four DB support people (and a few Apple support people) before Dave at DB had me try many other things, but finally solved it:  I simply had to trash the old copies of dropbox in my Finder.  Which I'd suspected was the problem, but none of the techs had me do it. Also, I *had* tried that when I had the same problem on my desktop in June, but it didn't solve it. 
And who knows, it could've been the order in which everything was done before that that made it work.  
I kept notes, so if anyone has any questions, I may be able to help.   I don't wish that timesuck on anyone.
