STORE PAGE - change items per row / mobile responsiveness

Hi,

When I open the site on my mobile phone, the Shop page looks terrible. Strange thing is that it doesn't display like this on the mobile view on Squarespace, just when I actually open it on my phone.

1. Products and buttons are on top of each other (see below)

2. Once I click to PRE-ORDER, the button copy goes back to "Add To Cart", and not PRE-ORDER

Ideally for MOBILE, the products should be 1 per row and centered.  I tried this code but it didn't work 😞

@media screen and (max-width:640px) {
.ProductList-grid .ProductList-item {
    width: 100% !important;
}
.ProductList-grid .ProductList-item img {
    width: 100% !important;
    height: auto !important;
    top: 0 !important;
    left: 0 !important;
}

}

Can anyone please help me?
