I have seen recommendations for Joplin. I downloaded it for Linux and Android (GrapheneOS). I created a note on desktop and transferred it to phone. I can’t find how to import the .jex file into the mobile app. That seems really dumb.
Am I the dumb one?
You have to sync folder that includes notes by choosing “file system” option in sync page in settings. You don’t need to import it. Sync notes to some folder on PC, transfer this folder to phone and sync it there.
