I tried switching to another note, but Joplin wouldn't allow it. After closing and reopening the app, I found that all data from the past few hours was lost in the current note. Can I get assistance in restoring it? It wasn't synced.
I have reviewed the history of the note and checked each version, but the content I spent hours writing is missing. It seems that after it ceased allowing me to switch between notes, the new entries were no longer recorded in the history
Unfortunately it does sound like there was some kind of error, I doubt there is a way of getting it back if it doesn't exist anywhere in the database after looking for some of its content. At most the log file might be useful to see what may have happened.
