Hello,

Thank you so much for purchasing our theme and contacting our support center.

Hello,

Sorry for the delay.

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
XTemos Studio
