I’m looking for a woocommerce hook that will run whenever the shipping option is changes, looks like
woocommerce_before_calculate_totals but also I need it run whenever shipping address is changed. I need this all to happen on the cart page. I have a ups for shipping, and when I change the shipping address the cart totals get updates but my
woocommerce_before_calculate_totals is not triggered it only gets triggered on shipping option change.
Any help is much appreciated.
