Here are two possible causes:
- The issue is still related to sync locks.
- Sync locks were removed, but only in v3.2.x. In v3.1.x, they need to be disabled using a feature flag (settings > synchronization > advanced > "enable sync locks").
- At least 1-2 users have reported that OneDrive sync is creating additional folders in
/AppsnamedGraph(orGraph 2or similar). If the sync folder changes from/Apps/Joplin->/Apps/Graph, this might cause sync issues:- Forum post with a related issue report.
- Upstream issue: Appfolder is named Graph · Issue #1866 · OneDrive/onedrive-api-docs · GitHub
- Joplin should sync to
/Apps/Joplin.
