I tried a "test run" on the site today. When I put in a shipping address using the computer it works just fine. When I put the same address using a cellphone, I get an error. It reads " 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. "
How do I fix this? I am using the same address for both computer and cellphone access to the website but only the computer view recognizes the address.
Did you include the same products on cart for both desktop and mobile sessions?
If you did, are you able to try and checkout using incognito mode on your mobile browser? You can also try on a different browser on your mobile, and clear your mobile browser's cache to rule out any browser caching issues.
If you included different products on cart, then you can double check if the products have been marked as a physical product within the product page on your store's Shopify admin. Check out the Shipping section of this help guide for more information on this.
I also went through some troubleshooting steps in regards to a similar shipping issue on this Forum post. You can go through the steps I listed on that post to see if that will resolve your issue.
