Win 11, QknP v R52.20
All discussions of this are closed with no answers. The linked billers is a very helpful addition to quicken until recently. I have now experienced this problem w/4 billers. Is there no solution except to unlink?
Have you tried turning off 2FA at each of these billers' websites? This might be a workaround until, if ever, this gets fixed properly.
Unfortunately this is not possible, message is that it cannot be disabled for any of these accounts.
If you haven't done so already, I'd say it's time to call Quicken Support on the phone during posted hours of operation and report a problem with each of these billers. Let them do a screen share session with you to review the situation on your computer, to determine the nature of the problem and to figure out how to fix it.
Unlinking those billers and paying the bills thru their respective websites using Autopay, APS, Direct Debit, etc. might the only other available workaround.
