Hello i wanted to test checkout in my store and i got this issue during the checkout ......This order can’t be shipped to the address you entered. Review your address to ensure that all fields have been entered correctly and try again.
Thank you for sharing your screenshots of what you are seeing and I am glad to hear you started troubleshooting this issue already.
If the areas I noted don't seem to be the root cause of the checkout issues I would ask that you please reach out to our live support for additional help. They will be able to go through your shipping settings and product details once they authenticate your account access and also loop in our Shipping support if needed.
