The Courier Guy

We are using the ShipLogic / The Courier Guy Shopify integration.

Issue:
When selecting "Create Shipment" on any Shopify order, the shipment page loads successfully but displays:

"Select a rate below, then click Continue. If no rates show, please check your order shipping address and your settings."

No rates are returned.

Troubleshooting already performed:

* Regenerated API key and reconnected
* Verified collection address configuration
* Verified customer shipping address
* Verified product weight and dimensions
* Manual shipment creation in ShipLogic portal works successfully
* Shopify app loads correctly and authenticates

Could you please check whether quote/rate requests for my are failing on the PayInlet side and whether there are any account mapping or authentication issues between the Shopify store and ShipLogic account?

Thank you.
