If you create a cart price rule for free shipping, it works on all shipping methods (Flat rate, table rates, ...) except in the UPS method. I have tried several configurations but nothing.
I have seen a thread in stackoverflow that is referenced: https://stackoverflow.com/questions/45936908/free-shipping-code-is-not-working-for-ups-for-magento-2
Although the answer gives solution to mark a UPS shipping method as free ALWAYS. I need it works only with the coupon.
Does anyone have a solution to this problem?
Thanks in advance.
