How to show add to cart in luma mobile theme?

Question

In Luma theme (mobile version), how can I show the "add to cart" button under the products ?

In desktop + tablet it's shown.

Edit :

version I'm working is from Magento 2.2.7, if it matters.

Thanks.

Answer 1

After some help, it happenned that css rule was disabled (product-item-actions). Installed directly from magento site, which is very strange. It's working now. Thanks for the help!

Answer 2

Is "Enable One Page Checkout" on or off? Stores -> Settings -> Configuration -> Sales -> Checkout -> Checkout Options
