Having this same problem with Wells Fargo. Was trying to reconnect to a View Only Wells Fargo account (I can log it and see accounts as well as download transactions but I have no access to actual funds). Kept failing. Tried again yesterday with the "master" Wells Fargo account (the one that created my View Only one) and it worked. A new screen popped up during the reconnect process, asking for a verification code sent to the phone number on file. My View Only WF account doesn't have this stuff; is that why it's failing? The View Only account used to work just fine. Has there been a security upgrade? Please fix this!
