we have an issue with our store,
if someone made an Order, then called us to make some edits to the order ( Add more products for example ), the shipping rates are not updated with the new order details.
to make it clear,
shipping price is based on total order value,
so for orders more than 100 USD, shipping is free
so if someone made an order with let's say 90 USD, shipping cost will be added.
now if they contacted us, after they created the order and asked to add more products,
now their new order value is 120USD
Expected, they would get free shipping, but shipping rate is still not updated
