Hi. I am running Joplin on my Android phone and a Linux desktop. I have set the Android client to use filesystem sync into a folder called ‘Joplin’ and I then use syncthing to sync that folder to the Linux box.
I did the same thing on the Linux client - file system sync, pointing to the synchronised folder on my hard drive.
If I add a new note on either client, I can see that the .md containing the note is synched to both copies of the Joplin folder but notes created on one device do not appear on the other, and vice-versa.
I feel sure I have missed something obvious but have no idea what.
