My shipping is set up correctly for shipping within United States. It was working appropriately 5/21/2020, A customer was able to Select shipping without any errors. Today 5/22/2020, no changes were made, and now customers are getting the error message that shipping is not available for address. Is there an issue on my end or is this a glitch? I have check the shipping options at least 5 time and have not seen any issues.
