Discount Code Issue (Invalid or Not Working)

If the discount codes stop working and are showing as invalid at the checkout:

Please make sure the GOAFFPRO App code in the Shopify discounts section is active (and not expired):

(Since all the discount codes are generated under it, it needs to be active)

If you are not able to find the GOAFFPRO app code in the Shopify discounts section (in the case it got deleted or removed): You can go to the Coupons > Automatic Coupons > Click on Click Here, to restore it.
