I have 2 Citibank Visa cards. A few weeks ago, Quicken gave a message about a change in the downloading that required confirming the connection through Quicken by logging in to the Citibank site. I did so and gave permissions for downloading both accounts. Ever since then, only one of the accounts downloads anything. The other appears to be perfectly set up and I can go through the update process with no errors or other issues, but it never returns transactions and shows a $0 online balance. I have reset it, deactivated it, and tried every method I know of but without success. These are both Costco branded Citi Visa cards, and the one that doesn't download transactions is associated with a Costco business account.
Is this a known problem? What should I try to restore transaction downloading?
