When I add more then one item that has a custom shipping it I get this error message “ Your cart has been updated and the items you added can’t be shipped to your address. Remove the items to complete your order.“ what can I do to make this go away?
Have you added the shipping zones and set up rates for these zones correctly? Also, can you confirm if you have inventory available for the location you have added? This issue occurs due to either of these two factors.
