Everyone who logs into QB must follow this procedure:

  • Sign in
  • Click Help
  • Go to Update QuickBooks
  • On the Overview page you need to see "Automatic Update is Off " in bold type
  • If you do not see that, you need to go to Options
  • click the No radio button for Automatic Update
  • click the Close button

That should solve the QB update pop-up message interference with the integration flows.
