Invalid folders - for no apparent reason

Just sent diagnostics - I’ve had a few of my synced folders stop syncing and they’re marked invalid after changing my dropbox email address associated with said dropbox account. I resented several folders without issue, but MISC, MUSIC, DESKTOP and SITES are marked as invalid. Not sure what to do - please advise.

Hi @ryan1,
The diagnostic is showing those areas as being already mounted and in conflict. I can’t tell why this would be the case, unfortunately.

If you right-click->remove sync from one of the folders and then try to re-add it, does it let you, or does it produce the same error?
