What issue do you have?

After upgrading to Joplin desktop v 3.6.14, the note history seems to have gone missing.

"Previous versions of this note" shows a blank page saying 'This note has no history".

No issues with that for me on the latest version. Have a look at Help > Synchronisation Status. Under the sync status heading, what is the count for Revision x/x?
