How to fIx out of stock notification in category page

Hello,

Try to use the code below for help:

.product-grid-item .wc_bis_loop_signup_prompt_container {
    display: none;
}

.wd-product.outofstock.wd-hover-alt:not(.wd-variation-active):is(.purchasable,.product-type-grouped):hover .swap-elements {
    transform: none;
}

Define it in Theme Settings -> Custom CSS.

Kind Regards
