Best Sync Method

[mmexdiscord]

What is the best syncing method, I primaily use MMEX on Android, but it is nice to use on the desktop now and then. Filen and Proton don't seem to allow for the SAF to work correctly.. I could spin up the webversion. It also looks like some folks use syncthing which is a pretty simple option. What is the simplest way to maintain a synced database across Fedora and Android? Or what has worked best for yourself? Thanks
