Can’t Remove Storefront breadcrumbs

[ Moved to the Fixing WordPress sub-forum. ]

Hi
I h’ve sent this question on storefront support page but no one answer me .

I have problem removing breadcrumbs with remove_action

i want to reposition storefront breadcrumbs
its already hooked in storefront_content_top
i added this line to my child theme function.php but its not working :

remove_action( ‘storefront_content_top’, ‘woocommerce_breadcrumb’, 10);

finally i removed it by commeting this line on storefront-woocommerce-template-hooks.php :

add_action( 'storefront_content_top', 'woocommerce_breadcrumb', 10 );

but its not safe and i will lose this change on theme update .

anyhelp will be appreciated
