Thanks, after a full Joplin reinstall I was clear for a little bit on my desktop machine. Then the same error happend again, I deleted the joplin-dekstop directory, tried to reopen, and now I cannot seem to re-synchronize with OneDrive. When I click the link to authenticate, I get redirected to log into my MS account, but then I am immediately redirected to an error page.
