Describe the bug and add attachments

There is an option (Delayed Shipping is not used) that was not used since PS 1.7.0.0 : https://github.com/PrestaShop/PrestaShop/blob/1.7.0.0/controllers/front/CartController.php At the moment, the configuration value PS_SHIP_WHEN_AVAILABLE is never used in the Core.

It was used in 1.6 : https://github.com/PrestaShop/PrestaShop-1.6/blob/14511463911e96906335135e46a249b5cf39f525/controllers/front/CartController.php#L188

Thanks @Progi1984 for the details ^^

Expected behavior

This option should work. Or should be deleted from the BO.

ping @PrestaShop/product-team what do you think ?

Steps to reproduce

1. Go to FO > Order a product > Order confirmation
2. Go to BO > Shop parameters > Shop settings > Enable Delayed Shipping option
3. Go to FO > Order a product > Order confirmation => See no difference with and without the option enabled in FO and BO
