We are unable to get any Shipping Methods to show on customer check out.
Checking out as a guest (call to
estimate-shipping-method) or as a registered user (call to
estimate-shipping-method-by-address-id) are returning empty arrays.
According to this... I am missing the email and region_code as required in the payload. On our live site the exact same payload is being delivered and working fine, missing those two attributes. We are upgrading a stage site to Magento 2.3.3 and the customer wants to remove the one-page checkout and use the default Magento check out.
We have tried many of the fixes found through research and nothing seems to be helping at this time. I am not sure what information you will need, so please feel free to ask and I will update with the information as soon as I am able.
