We have an Apple Pay account and have successfully created and verified the payment processing certificate in our Apple Developer account.
When initiating an Apple Pay payment, the Apple session is created successfully with the correct data return from api , but it is not accepted with the error: “Payment not completed.”
The issue occurs even though the merchant validation step works without errors.
Our websites where this is happening are:

Could you please help us identify the cause of the issue and guide us on resolving it?
