I'm selling only 1 digital item on my woocommerce store and use this link from the landing page so the user lands directly in the checkout page: domain.com/checkout/?add-to-cart=11
The digital product is set to "Sold Individually".
When I add the product for the first time it works fine, but if I add it again, the checkout page displays
There are some issues with the items in your cart. Please go back to the cart page and resolve these issues before checking out. without any checkout fields or payment options.
