The way the app works is that it adds a variant every time a customer adds a product to the cart through the calculator.

Deleting Variants

As Shopify sets a limit to how many variants a specific product can have (100 variants) we go through all the variants every 2 hours and delete them to make sure you don't surpass that number. However, this may cause the products lying in the cart to disappear after two hours. However, due to this customers are not able to complete the checkout if they have abandoned the cart for more than two hours.

To keep the products in the cart for a longer duration, you can go to configuration settings and switch on the toggle that keeps the variants alive until the limit of 100 variants is breached, irrespective of the time duration. For e.g., if the customer returns to the abandoned cart even after 24 hours and the variant limit of 100 has not been reached yet, then the customer would be able to checkout the product.
