The synchronize option is not visible in Premier 2021.   I have 5 credit cards--one bank-one statement.  It WAS working just fine synchronizing with my bank then all of a sudden it would not download anything. I spend over an hour with QB tech--who was very difficult to understand- After having be complete steps that made no difference, his final response was that he couldn't help me because I didn't have a new QB account and he couldn't see my screen and he would email me me a way to correct it.  Sure.......I never received anything and I still have the same issue.
