NextCloud with SMB Sync Error

I’m having trouble syncing Joplin using NextCloud. I think the error is due to this bug in NC – https://github.com/nextcloud/server/issues/9663 – as the folder I’m trying to sync to is in an external storage (SMB) NC folder. Sync works fine if I use a non-external NC folder.

If anyone has Ideas for fixes or workarounds, it would be appreciated.

Last error: Error: MKCOL .sync/: Could not create directory /Central/Documents/ Personal/Information/Notetaking/.sync (Exception Sabre\DAV\Exception\Forbidden) (403): <?xml version="1.0" encoding="utf-8"?>
<d:error xmlns:d=“DAV:” xmlns:s= “http://sabredav.org/ns”>

Yes that seems to be something for Nextcloud to fix. Although if I could, I’d change the sync structure and change this dot directories to regular ones as they cause various issues.

Just for reference – what specifically is preventing the switch to regular directories?
(e.g. technological limitations, backward compatibility, the time it would take to re-code everything, etc.)
