DTTG stuck verifying inbox

My DTTG app is showing a “full” progress circle, with a message saying “verifying inboxes”. It stays like this. Sync activities are continuing to occur, but then this message returns.

Is this recoverable, or do I need to blow away my synced databases and start again?

This is definitely nothing serious that requires nuking your databases and starting over. Could you send us the logs via ? > Contact us with a reference to this thread? Then we have everything to look into it from development.
