Here are a couple of things that I found in the cart. When I use the shipping calculator, it works fine on the first pass. However, If I change the order qty on the checkout page, the shipping does not automatically recalculate. I need to click the change address button and force the recalc. I worry that customers will not do this and then checkout with the wrong shipping amount.
Also, if I continue to shop and add things to my cart the ability to change the ship method or address is no longer on the screen so I can't recalcu the shipping.
I am using version 2.93
Thanks
Carl
