I need to enable free shipping on all orders with no other discount dependency
I tried using blank coupon with 0% discount and apply the free shipping
Made sure that the “require free shipping coupon” is checked in the shipping section.
That should be enough. Can you temporarily enable debug mode from our plugin’s Settings-page and then send us the json that appears if you click ‘Coupon Data as Json’ on the coupon’s Miscellaneous tab?
