Thanks for the information. I still go back to the fact that I can connect my Citibank card via bank feeds in my newly created company but not in my existing company file, which I've used in Quickbooks for fifteen years. This points to a QuickBooks, not a Citibank issue.  I don't have the energy to call support again, it's 1-2 hours my day that I cannot spare. I hope someone finds a solution and posts it.
