I had someone add "Add to Cart" button on collection pages a while ago, and I just realized it's adding a wrong item to the cart. According to Shopify support, it is adding the last item on the Related Products list, and "likely caused by the custom code ... for the Related Products list's Add to Cart buttons.
Can someone please fix this for me?
