Coupon & Discount Functionality
Discount Not Applying
Double-check the discount configuration for the specific user role.
Ensure the user is logged in with the correct role to receive the discount.
Verify that the targeted product(s) are included in the discount settings. Some exclusions might be applied.
Coupons Not Restricted
Confirm that the chosen user roles are selected for coupon restriction in the plugin settings.
Make sure the coupon code itself isn’t malfunctioning. Try creating a new test coupon to isolate the issue.
