Okay, I’ve tried the standard “gettext” method and the woocommerce_shipping_package_name filter method with no luck. The gettext changed the “Shipping” label to “Delivery” in every place but the cart and check out pages where I intended, particularly it showed up on the Woocommerce/Settings tab on the dashboard.
So the question I have is "On the Cart and Checkout pages in Woocommerce working in Pro, how do you change “Shipping” to “Delivery”? I have a child theme of Pro and have specified the cart page, 'if (is_cart()) {//run function} to remove from dashboard but still no luck. please help.
