I am trying to setup UPS XML method for Shipping Rates, and it seems to work for any address in California. When I try an address outside of California, I do not get any shipping rates back.
So I looked at the Magento debug.log and saw the below response. My assumption is that it is replacing the StateProvinceCode for CA when its sending the request to UPS.
I looked at the following link https://github.com/magento/magento2/issues/6875 thinking the issue could be fixed, but its still ignoring the region in the Shipping Method.
