Just the new version lost the icon associated with one of my vaults. I let it sit for a while (days and days of simple laziness really). Was able to force a new sync by going into the web UI pretending I wanted to edit my icon and then just clicking save.
Just FYI, Otherwise, for me at least, no issues.
