I too have not been able to connect to Citi cards since August 30th. This capability is necessary to operate my business.  We will discontinue using the Costco Visa card.  I spent my career in IT - there is NO excuse that this hasn't been fixed (26 days and counting) and isn't a priority for Intuit to correct.  When enough people complain to Citi Cards and stop using their Visa cards perhaps Intuit will find a fix!  I have been using Quick Books for 17 years - first time for an issue unresolved for so long.
