Nayeem,
Thank you for your support.
I noticed that you have created a new page named wpdm-cart in order to settle the purchase tunnel.
This purchase tunnel is works exclusively for wpdm product and does not interacts with the woocommerce cart page.
I would like to now if it’s possible to actually redirect “wpdm products” to the woocommerce cart that I use by default for other physical products.
Best regards
