I have a similar problem to the ones already reported with Dropbox sync stalling silently. DT3 seems to think all is well, and DTTG reports all databases as synced but nothing gets synced onto my phone. I have seen a few posts saying that this was just a Dropbox problem. That may be true, but DTTG needs to handle this better:
When this happens, some databases silently fall out of sync but DTTG’s list of databases in the dropbox store continues to update the last synced timestamps. BUT: if I uninstall and reinstall DTTG and reconnect the sync store, the affected databases don’t even show up in the list of remote databases. So upon reconnect, DTTG recognizes that something is wrong with those databases. It should be able to do so without me having to do that.
Is the official recommendation for now to not use Dropbox sync?
