If you are either able to send me (via a ticket/email) a screenshot of how you've configured WebDAV on the Settings tab - or what look like the relevant parts of the debug log (see https://beorg.app/support/debug/) I'll take a look.
What's your email?
If you'd like to email directly use mgkennard@appsonthemove.com.
Sent, And Thanks very much for your help
