Had a chance to update QB today and then I was able to set up the bank feed for Citibank which was tortuous as finding that screen to authorize the link was not trivial so I am posting it here to help future users avoid tearing out their hair as I did today. You're welcome!

Once you are logged into Citibank go to:  https://online.citi.com/US/ag/ofxConsentPage

Once I clicked on the Add to allow me to login, it all moved forward smoothly as in the past. I honestly can't believe the way this thread was handled and this should be used as an example for customer service management as to how not to handle a serious problem.
