I had the same issue, called QB customer service gave me the run around. After they realized that with a new company file there is no issue connecting to Citi cards. They took my Company file removed all the Bank Feeds and sent me back the file. I had re-connect all my other bank feeds again along with Citi cards. worked for one day and the very next day same error came back!! Back to square one, I still cannot down Citi credit card transactions directly
