New is a fix for a crash on macOS which occurred on exit. Additionally there are improvements for dragging entries to move / copy, Quick Unlock is automatically enabled when unlocked for Auto-Type or browser access, and the Auto-Type button and shortcut are disabled when the Auto-Type setting is disabled for the entry or group. Complete Changelog is available on https://github.com/keepassxreboot/keepassxc/releases/tag/2.7.6
It works for every user. Be sure to grant SAF privileges to the app and the folder. Then you can open the mount from the left handed files application drawer. For example from within KeePassDX, click on “Open existing database” > the system “files” app opens > click the hamburger menu in “files” > find the Webdav mount on the bottom in the drawer > the Webdav share opens > navigate to the database > click it > voila it opens in KeePassDX. If you now change the entries > it’s saved directly to the Webdav share.
Sounds a lot of clicks, but you will get used to it, after a short while. It’s the same as any other mount like Onedrive, Google drive or Dropbox. Very easy.

There is also a YouTube video, explaining everything.
