I keep seeing a red exclamation flag on the Dropbox icon.

The red icon doesnt replicate online or to other devices. So it only shows on the device having an issue.

If you go to the app and click on the icon and then click on your little name/image/letters at top right you can see a menu saying 'Sync Issues'. Have you checked that?

Yes, repeatedly. And there are no sync issues.

Hey Robert T.30, can you click on the Dropbox icon again and send me a screenshot of the window you see next? I’d like to have a visual and see what we can try from there.

As requested

Hey Robert T.30, thanks for the screenshot!

It might sound trivial, but have you checked on the little bell icon on your top right, to make sure you have no notifications there?

If you have rebooted your computer and still see the red icon on the app on your system tray, could you please try re-installing the app using the installer from this link?

It's got to be something unique to my account: I completely uninstalled and then reinstalled Dropbox, and the red flag showed up immediately, although my files are there.

Hey Robert T.30, I see on the screenshot a "keep your Mac files backed up" notification; if you click on "close", does the red exclamation icon go away?

Hi Robert T.30 

I actually dont think thats an ! its a notification (1).

I had a similar issue on a mac that it just wouldn't go away. Its worth clicking on the bell icon though and seeing if anything is in that 🙂

This is very irritating - I've repeatedly checked for any reason for the red flag, and there's nothing; and this is true after completely uninstalling and reinstalling it.

I assume Dropbox is too perfect a company to acknowledge their bugs? Let alone fix them?
