There are a couple of ways to remove related products.
Add the following PHP code to the functions.php file of a child theme remove_action( 'woocommerce_after_single_product_summary', 'woocommerce_output_related_products', 20 );
this is the “correct” way to remove related products from the template
Add the following CSS in Customize > Additional CSS
this will not remove the related products, only hides the section from view
If you can wait couple of days, I’ll see if we can add this as an option to the theme.
