On Jan-17-2019 had no problems downloading manually my Chase credit card file and importing the QBO into Quickbooks. As of Jan-25-2019, got an error message:

"QBO download will not load in Quickbooks. Error message is: Quickbooks is unable to verify the Financial Instituation information for this download. Please try again later."

After looking at a recent successful download, I found this significant difference in one line:

<INTU.BID>2430 <-- good QBO

<INTU.BID>10898 <-- bad QBO

Changing the number to 2430 in bad QBO file made the import correctly. Not sure who is at fault here, Chase or Quickbooks. Hope this helps someone else. I answered my own question.
