In order to remove breadcrumbs from the Storefront theme, the documentation states to add the following in functions.php:
remove_action( 'woocommerce_before_main_content', 'woocommerce_breadcrumb', 20 );
I tried this in a child theme of Storefront and it doesn't work. Tracing back the woocommerce_breadcrumb, it seems to be added in storefront_content_top action (in the file <storefront_dir>/inc/woocommerce/storefront-woocommerce-template-hooks.php. I commented out the corresponding line and indeed the breadcrumbs are hidden.
However, to do this the right way, I try to disable it from the child theme using
remove_action( 'storefront_content_top', 'woocommerce_breadcrumb', 10 );
but it doesn't work. I should clarify that I test this in a fresh child theme with no other code.
How would one disable the breadcrumbs from a child theme?
