I'm having real issues completing a sync to Android (actively syncs+decrypts until crash - always crashes at the same point). Two Windows PCs syncing just fine, but two Android phones crashing every time it's opened (unless I switch off internet first). Tried so many ways to fix it, and finally this sounds very much like my issue.
Do I need to delete that folder you describe on Android, or also delete all traces from Windows (in which case, do I need to export to JEX, delete, sync the deletions to Joplin Cloud, re-import from JEX?)
Thanks for your help!
