Please note: Our app will not work with default Shopify variants and sometimes this is the reason for slow-add-to-cart. We can offer your options through our app by using a dropdown or image selector element. When your calculator creates a priced item, Apippa needs to know how to represent it as a Shopify variant so the correct price and SKU reach the cart and order. This article explains the Variant Location and SKU settings.
