All my notes are syncing between my Win 7 PC, Win 8.1 laptop and Samsung Galaxy S2 phone with Android 4.1.2. All except one note that is not showing as updating since May of last year on the phone. It is updated on the laptop okay. I solved the problem by creating a new note on the PC and copy/paste into it from the old one. I added "2" on the end of the title so I can be sure to use that one when I add info. This was a workaround that worked, but I'd like to know how this happened.
