I've been using KeePass with Syncthing for 5+ years now and I think I've only had a sync issue once in all this time.
Granted I do make sure I only use the database on one device at a time (so not making edits on desktop and my phone at the same time) and I'm using XC and DX clients not the OG KeePass program.
I'm curious what is causing sync issues to make it "common", I use my db every day.
