The Dropbox icon in my menu bar has shown the syncing icon for days. I've tried restarting the app as well as restarting my computer. When Dropbox starts up, it says "Syncing 2 files..." for a little while and then changes to simply "Syncing...". This is the message at the bottom of the Dropbox dropdown. When I select "View syncing issues" it reports "No Issues". I have the 2TB plan and am nowhere near running out of space, either on my plan or on my hard drive.
As far as I can tell, Dropbox is working properly otherwise.
The time on my computer is set automatically and is correct. I have not travelled or changed the time. I use regular home high-speed internet with no special settings. I've not had this issue in the past, nor do I have issues with other apps.
I have version v213.4.4597 and have been using File Provider (CloudStorage) for a while now.
