I have used Keepass password database on dropbox for many years without issue. A few months ago it stopped syncing properly. If I make a change in Keepass, I see that dropbox thinks it updated all copies as the file date changes, however when opening up the file, I see my updates haven't changed. I have gone through all of the published trouble shooting procedures, including uninstalling and reinstalling dropbox, replacing the kdbx database file, and checking file permissions. Any ideas?
