This problem has just continued to spread over the past year as I have more and more banks that I have previously been able to connect to, now giving me this "Did you mistype your sign-in info?" error.
Banks at this point include:
Three Rivers FCU, EdFinancial Services, Home Depot (Citibank), Kohl's, Military Star, PayPal, Target, & Mr. Cooper. I know these all have the capability as one of the competitor apps does the downloads with no issues.
