This configuration does not sync between all three clients, no encryption activated:
(1) Win10 client
(2) First Android 10 client
(3) Second Android 10 client
All are pointing to the very same WebDAV ressource.
(1) and (2) sync fine. Notes entered in (3) do not show up in the other clients. Neither do the notes of (1) and (2) show up in (3). All three clients confirm the sync to be completed.
Yes, I have the same problem.
I searched the file name on server, it exist.
I clicked the "note properties" button of the not-sync-note on client (3), then all clients can sync
I am sure you have done this already, but could you please "one more time" carefully compare all settings on both Android devices, including : network, firewall (?), VPN (?), Joplin, etc .
Then goto the log files and check for error messages.
and report back ?
