Prestashop - Coupon does not apply to combinations

Hello,

We have recently added different colors to our products using Prestashop Combinations. It appears that the coupon does not work if one of the combinations is selected. Can you advise how we apply it to all variations too?

Nothing special.  I assume the coupon selects the specific product?  Just make sure it does not select a specific combination.

Also debug the coupon by going to awocoupon > configuration > error messages, clicking debug and saving and see why it is failing in the front end.
