I am still using QBD 2020 Prem.

I have a Capital One CC, which allows export of a QBO file. On the CC web-site when I select the file type even refers to QB with type QBO.

I got the import to work once, saw my transactions, but when I now try to import the QBO I get a popup (see attachment), that I am using an account type that QB does not support. Well, QBO were supported for the longest time, plus, QBO for CC should be supported as well.

I checked the QBO details, and it sure looks like a correct file, having the correct CC identifiers mating the value in the QB account.

The popup tells me to contact my financial institution, but I know the QBO is correct.

Can somebody tell me what the problem is?
