For a long time, I used Syncthing for my Joplin notes. It was running as a Docker image on my TrueNAS server. The notes themselves were on the TrueNAS server, and from there, Syncthing would sync it to my PC and laptop, for example.
I am annoyed, however, at some desyncing issues. Have you guys got ideas on how to better solve this?
What issues exactly? I found Syncthing to be 99% reliable. The rest is manually fixed with .stversion folder diffing.
