This was a huge help to me too!  However, I did find that I needed to do a couple of preliminary steps.

I'm using QuickBooks Desktop Pro Plus 2022.  In my case, I had two credit cards with Bank of America that had been using Web Connect and one that had been downloading automatically; but, the downloading had failed.

The preliminary steps were to:

1. From the main QuickBooks Desktop Menu do:  Banking > Bank Feeds > Bank Feeds Center

2. Using each account 'tile?', "Disable bank feeds" for each account associated with the bank for which I was having trouble.

3. From the main QuickBooks Desktop Menu do:  Help > Reset Intuit ID Settings.

4. Follow the steps provided by Sarah PECO1.

This worked for me. Good luck to everyone.
