For reference, support-category thread OneDrive Sync Question
Apparently it is necessary to completely backup and restore the entire Joplin database when a OneDrive authentication token is revoked or expires.
I would request a supported method of re-authenticating with OneDrive when Joplin's token is revoked or expires- as I mentioned in the other thread, backing up and restoring your entire database annually (when the OneDrive token expires) isn't really practical for production software.
Less important, but very useful, would be an option to choose which instance of OneDrive (business or personal) is used to authenticate. I don't know the details without looking into the OneDrive API, but certainly many apps do allow making this choice, and it would be a convenience.
