CapitalOne: You Have No Eligible Accounts to Share
Found at:
"SOLVED: all active accounts, all working previously with quicken. HOWEVER, there was a fraud alert on the account (added additional cell #), so CapitalOne shut down any interconnections until that was validated by calling customer service. 5 Mins after confirming information was legit, reauthorization resumed without any issues."
Confirming, once again, that it's a mistake to jump to conclusions.
And in this case, a call to the financial institution would have solved the problem over 10 days ago.
