Show Related Products Based On Categories Only

Replies: 0

Hi,
I want To Show Related Products Based On Categories Only (without tags),

I tried using woocommerce_product_related_posts_relate_by_tag filter in functions.php file by this way :

add_filter( ‘woocommerce_product_related_posts_relate_by_tag’, function() {
return false;
});

But nothing change,

Any suggestions to make that happen without other plugins?
