Ah yeah, the fun of how that works. I recall that I had previously set up WebDAV to try to simplify my source of truth but I think that was just with the original KeePass app, not KeePassXC. I also wasn’t trying to share passwords among multiple people but I do recall having issues when I was using Dropbox to sync to my phone since I would have to actually make sure Dropbox had updated the copy of the file which required me opening the app at the time.
