  IMPORTANT: you must ensure that you enable the Rating API during the application setup process. 
  When viewing your completed Pressero App Info / Credentials page, if you check under the Product In Use section, you should see a row called "Rating" with the value "Approved" (as in the previous image).
  If you do not, please re-initiate the process to obtain new credentials, and ensure you enable the Rating API. If the Rating API is not enabled, you will experience issues successfully pulling shipment rates for all sites actively using any UPS V2 shipping method.
