I have a custom product detail page. This page uses a perch custom template.
When I click "Add to Cart" from product detail page, it takes me to the cart and displays the product. When I click "Remove from cart", the item/s in the cart disappears.
If I go back to the product detail page and click "Add to Cart" again, the cart is still empty.
How do I stop cart from being empty when I click the "Add to Cart" button again?
