I try many times to setup and test the % discount with Coupon but unlucky. Could you advise me how to do it properly?
1. Setup a new 10% off discount by a coupon code 'FPUR10' with effective date range from 1 Nov 2023 t0 22 Nov 2023.
2. Go to make new order and put the discount code 'FPUR10'
3. it returns as "The coupon code you entered couldn't be applied to your order" after clikc apply coupon
Please help. Many thanks.
