When I check the shipping via table rate for products ordered in the cart page in my magento 2.3.4 site, it comes out fine but on the checkout page, I get the errors in the image below.
I have reviewed the table rates and the configuration , all checks out fine. the cart rules are all fine.
In the checkout page, when I insert the post code and the rest of the address fields, I keep getting the same error for both the FLAT RATE and TABLE RATE.
I need your assistance.
