No the upgrade did not fix it for me either. Not sure how this sync issue keeps re-occurring through out the years, keeps getting fixed (supposedly) and keeps coming back again. Don’t believe me, do a search in this forum..
I don’t think is too much to ask for a premium product to work as intended. I understand issues happen but when when they keep re-occurring for years, impeded the use of a premium software and it takes an enormous amount of time to fix; not sure how acceptable that is!
