Hi! in single product page I'd like to move the "additional information" tab under add to cart button.

I've already achieved that with php code:

 // Remove additional information tab
add_filter( 'woocommerce_product_tabs', 'remove_additional_information_tab', 100, 1 );
function remove_additional_information_tab( $tabs ) {
    unset($tabs['additional_information']);

    return $tabs;
}

// Add "additional information" after add to cart
add_action( 'woocommerce_single_product_summary', 'additional_info_under_product_meta', 45 );
function additional_info_under_product_meta() {
    global $product;

    if ( $product && ( $product->has_attributes() || apply_filters( 'wc_product_enable_dimensions_display', $product->has_weight() || $product->has_dimensions() ) ) ) {
        wc_display_product_attributes( $product );
    }
}

But, as you can see, it doesn't work anymore (the "informazioni aggiuntive" tab is now under page content). 

Can you please tell me what doesn't work fine? what could be changed? I didn't edit the php code at all

Thank you
