How to change number of Related Products? (WC 3)

I think I have tried all options – but I just can not change the number of Related Products in WooCommerce 3.0.4.

I hoped the most promising snippet would be the one that can be found in the docs: “Change number of related products output”
```
function woo_related_products_limit() {
  global $product;
	
	$args['posts_per_page'] = 6;
	return $args;
}
add_filter( 'woocommerce_output_related_products_args', 'jk_related_products_args' );
  function jk_related_products_args( $args ) {
	$args['posts_per_page'] = 4; // 4 related products
	$args['columns'] = 2; // arranged in 2 columns
	return $args;
}
```
I put it into the functions.php of my storefront child theme but it just doesn’t have any effect on the number of items displayed. Any pointers / suggestions appreciated. Thank you!

ok – found it: I hooked into the woocommerce_output_related_products_args filter – the priority (99) is important since some other function was probably always setting the number to 3. So now I have this in the functions.php of my storefront child theme:

add_filter( 'woocommerce_output_related_products_args', 'hff_commerce_child_related_products_args', 99, 3 );
 
  function hff_commerce_child_related_products_args( $args ) {
	  
	//  echo("RELATED :::");
    $args = array( 
        'posts_per_page' => 4,  
        'columns' => 4,  
        'orderby' => 'DESC',  
 ); 
 	return $args;
}

…and it works…
