    Hello @dsander,

    Thank you for sharing your experience. To help troubleshoot this issue, please provide more information. Are you seeing this error in Quicken, or are you seeing this error on Citi's website, when trying to authorize the account?

    If you are seeing this on Citi's website, which browser are you using? Please make sure browser extensions (especially ad blockers and pop-up blockers) are paused. If you haven't already done so, please also try temporarily setting a different default browser (do not use Brave or DuckDuckGo, since they are known to cause issues when authorizing accounts to connect in Quicken).

    I look forward to your response!
