Note: Be careful posting a full log
Be careful sharing logs if using the OneDrive sync target — see token logging issue.
Qualifications: 1. Joplin didn't log entire authorization tokens (just the start, but still a large portion of the token) and 2. these tokens should expire after a few days. (To be safe, though, I still suggest reviewing the log.)
Questions
- Does the UI freeze? (For example, can notes be opened and edited?)
- Is end-to-end encryption enabled?
Suggestions
- If it's an attachment that's failing to sync, turning off automatic attachment download might help.
