I sell online courses and utilize the ecommerce store and there's a lot of issues with the product details page. 1. the product details element is anchored to that page so you can only use the element there and that's it. 2. There is limited customization to the element itself (no one will buy more than one quantity of a digital good). 3. I have multiple products but the elements added to the product details page shows on all of my products from the product list. It doesn't make sense to have information about one product show on a different product. 4. You cannot clone the product details page to fix these issues. 5. There should be a add to cart action to any button element as this would also remedy limitations of the product details element as digital goods do not need variants, quantities, etc.
