Cannot connect all of my Bank of America credit cards

My company has 6 Bank of America credit cards (6 employees have a card with their name). All of these individual credit cards are subaccounts that roll up to an umbrella cc account at BofA - which is the master account that we pay down each month.

Previously, we were able to connect each individual account to QBO and download their transactions. In fact, 4 of the current 6 cards have been in Quickbooks for years and are still downloading transactions from BofA. However, 2 of the 6 are new cards, and I'm no longer seeing the ability to add them. When I try to add the accounts by re-connecting through BofA, it's saying that I've already connected all the accounts, even though there are still two cards that I clearly haven't.

After calling into QBO support, they said that QBO changed their processes so that I have to connect the umbrella account that I mentioned earlier, rather than the individual accounts. I reluctantly connected the umbrella account (knowing I'd have to adjust some items in my chart of accounts), and in doing this, I assumed that all transactions from all the credit cards would come in through that account — it would not have been ideal, but I could live with it. But that's not even the case. It's only downloading the credit card payments and any finance charges (not the transactions from the individual credit cards).

Has anyone experienced this before? If, going forward, there will be no way of auto-downloading any new individual credit cards — forcing me to add every transaction manually — then that starts to become a dealbreaker and might force me to look at other accounting software. Thanks in advance for any help here!
