“Store notices options” is an element created for the single product page and can be used only on a single product page. If you are using it on another page it will not display and not be of any help.
When you hit the “Add to cart” button from a single product page, you are notified by WordPress that your item has been added to your cart. This element represents exactly that notification.
!Important The “Store notices options” must be used inside the “single product page” element.
