What issue do you have?
I've had WebDav multi sync between a desktop, laptop and mobile going well for over a year.
I got a new phone. yay. On my desktop, I backed up to a JEX file.
I configured WebDav in Joplin on Android and tested the connection. Good.
I did the first sync, which took about 13 minutes for 2400 items.
I did another sync, and it stepped through and deleted under 800 remote items. Maybe 5 minutes. I noticed files getting deleted in a browser view of the webdav file space. These were the uniquely named .md files.
On an old phone, I sync'd, and looked normal: created a few local items; 1 remote item, fetched 10, and done. Took 13 seconds.
The laptop had similar sync stats to the older android.
What might have been the 800 remote items (the uniquely named *.md files) that were deleted by the new phone on the webdav server? Orphaned data?
