After a quickdive into the code, from

• https://github.com/woocommerce/woocommerce/blob/trunk/plugins/woocommerce/includes/class-wc-checkout.php#L726 to
• https://github.com/woocommerce/woocommerce/blob/trunk/plugins/woocommerce/includes/class-wc-cart.php#L1549 to
• https://github.com/woocommerce/woocommerce/blob/trunk/plugins/woocommerce/includes/class-wc-cart.php#L1528 and to
• https://github.com/woocommerce/woocommerce/blob/trunk/plugins/woocommerce/includes/abstracts/abstract-wc-product.php#L1671

I realized that ignoring the shipping address only works for virtual products. Mind you regardless of whether the customer has checked the box for a different shipping address or not.

This does not make much sense to me. In most cases billing address and shipping address match. For the remaining cases, the customer should check the box that it should be sent to a different shipping address and fill in or correct the form fields.
