is it possible to show the shipping costs in the cart summary on the right side of the shopping cart? From what I have seen in the cart-totals.php it should be. I’ve already tried switching off all plugins and changed to theme twenty-seventeen, but it didn’t work.
As you want to display the shipping field values in the shipping calculator. Actually it autofills with the help of cache. When the customer completes an order and then the same customer uses the same device to order something else then that field auto fills via browser cache.
Please disable all third party plugins and activate some default WordPress theme just to check whether the issue is with our theme or not because it’s a part of default WooCommerce functionality and our theme does not influence this.
