After a month of trying to reconnect my Chase card to QB bank feeds, I tried again today and it's working now. No clue as to why, but someone either on QB's end or Chase's end must have fixed something. I didn't do anything different, just went through the process of adding bank feeds to my account, connecting the card, and then my transactions downloaded. Previously, I would go through the setup and it would say it was connected, but then no transactions would ever download. I knew nothing changed with Chase's permissions, despite what Intuit said, because I still have another card that syncs fine with a different QB account. It might not work for everyone, but maybe try setting it up again.
