QB Issue Resolution:
If you wait for several minutes does it come up with an alert showing an error? Sometimes bank and credit card web sites have issues with traffic.
If you have more than one account online, try selecting one at a time from the pop up on the left top of the Download Transactions window. Then press the “download” button (but not “download all”). This may enable you to download from the other accounts (and also figure out which account is currently experiencing difficulty).
Or it could be something else – but this is what comes to mind.
