I will call QBO support and talk to a human for the 2nd time about not being able to connect.  I have a minimum of 4 case numbers on this issue and will make sure that they are all linked to "INV-100733" as you suggest.  Case #15113534247, #15113534199, #15113534215, #15113534130.  The last representative I spoke with did not mention the "INV-100733."

The root cause appears to be that nb.fidelity.com website, when I go to directly, I can log in.  When I use QBO to link an account and it redirects me to that website I get a pop-up to have me give permission to QBO to access the data.  I don't get that popup when I login directly at the same web link.  I'm wondering if that is the root cause??  As a ProAdvisor, CPA during tax season, I would like to request that this issue be escalated.
