I used to sync using triggers over OneDrive. A while ago now, but they updated the application to handle synchronisation better and it’s pretty much baked in. KeePassXC is even better in that it can reload your database the second it detects changes.

I really do like KeePass, it features one thing many other (any?) applications don’t offer and that’s auto-typing your credentials into applications. For this reason alone I still use KeePass heavily at my workplace.
