No longer see syncing check marks on Mac when using the Dropbox desktop app

Thanks for the response.

Running Sequoia 15.1.1

From the menu bar, Dropbox 213.4.4597.  Says Up To Date.  Also says all files are up to date.  For what it's worth, each time I quit and re-start dropbox, there is a small activity icon in the menu bar for like 7 to 10 seconds, then it disappears.  No other check marks or status symbols anywhere. 

On the 3rd party apps, I do use an online backup system (BackBlaze) that I have used for many years alongside Dropbox.  I tried to check if dropbox was excluded from back blaze and I do not see how to exclude that entire folder.  Still playing around with it.  Can't think of any other apps that would be involved.  I don't have many apps installed in general outside the typical Apple apps. 

I will work on a pic separately but I basically have two folders with no icons.   

Update:  I was able to "exclude" the Dropbox folder from both Backblaze and Time Machine.  Time Machine has backed up that location I assume for years but I excluded it to test.   Quit dropbox, restarted it and Finder.  No difference.  I do still see a very quick status icon in the menu bar but it goes away very quickly.   Here's a pic of my folder.
