Prevent product to be added to cart if shipping is not compatible with products already in cart

[Mercader Virtual]

Hi,

This is the situation:

I have Product A that can be shipped only with Carrier 1.
I also have Product B, but this one can only be shipped with Carrier 2.

If user adds Product A to cart, I would like to throw an error and prevent the user to add Product B to cart, since there's a mismatch with the carriers.

Prestashop 1.7.5.1 allows both products to be added but it doesn't show any carrier available, I guess because the incompatibility. This represents a serious UX problem since user doesn't have a clue what's going on, which will result in a lost customer.

By preventing the user to add an incompatible product to cart, and letting her know why the product can't be added, will improve a lot the shopping experience.

I will appreciate any comments on this matter.

Thanks.

Did you managed to solve this? I am looking for something very similar!

Any solution can works perfectly when the customer choose the carrier. You cannot check when the user add to cart, if no carrier selected. You mean, the 1rst product put in cart determines the carrier?
