Add to cart button loading items to cart very very very slow or not at all

Hello,

Try to add the following PHP code snippet to the child theme functions.php file to fix this

add_filter('woocommerce_add_to_cart_redirect', function( $url ) {
	if( strpos( $url, 'product-added-to-cart' ) > 0 || strpos( $url, 'product_added_to_cart' ) > 0) {
		if ( isset( $_REQUEST['wd-add-to-cart'] ) ) {
			return wc_get_checkout_url();
		}
		return '';
	} 
	return $url;
 }, PHP_INT_MAX);

Kind Regards
