We have an internal CRM that uses QuickBooks API and it's NOT PUBLICLY AVAILABLE to anyone except 3 people. We strictly only use it to create invoices every 1st,10th,15th,20th and nothing else. Then today we are denied access to the API again even though our refresh tokens are still valid. This already happened back in February, we were shut down because of a new Platform Requirements which I happily filled out and then upon submission, were denied without a reason and CANNOT resubmit the form. Then later that day it was fixed as you said it was cause of an outage affecting US clients.

Today, it probably ran for a few hours and stopped working. I visited the Dashboard to get a new Refresh tokens and still cannot proceed cause it says NOT APPROVED.
