still on 10.65.3 and met an "old friend", a still not fixed bug, even I was off for 9 months...
Seems completed actions are still getting out of sync from time to time. While the todo is completed in the note, it constantly reappears in the home screen and in the todo view as still open. On all devices incl. Web-App.
I tried dozens of re-syncs, note edits, to force that change synced to everywhere within the elephant. No chance to fix that. Exactly that bug was the reason to leave Evernote!
