Weird warning on sync

[Anonym Potato]

Hello, I just managed to enable webdav, but it still won't sync. I entered the right url username and password.

I get an message:
"Sync Error      Password of data on WebDAV is required"

When I tap on Resolve, I can enter the webdav  password again.

Afterwards it gives me an weird message:
"Please note that after the sync, the password of data on WebDAV will be changed to password of "Tresor-Name" vault."

What does this mean? What can I do?

I am using an iPhone XR on the latest iOS version.

I just understood, that the problem was, that on the webdav was another db file.

Problem solved.
