Same issue. Edits to note don’t save. Edits appear so long as app (Ver. 10.2) is open, but vanish after closing and reopening. If I open that note on desktop and make the same edits they save on Evernote desktop. Then going back to iPad I get a ‘Note Conflict. A copy was made’ and see two copies of the note - one has the edits, the other doesn’t. I trust if I delete the one without the edits nothing will happen to the copy with the edits.
In any case, the issue is clearly a problem that needs resolution.
