Why does the page say that we should use this function on the add_meta_boxes action hook, but all the examples show admin_menu as the action being hooked? Ancawonka 08:23, 26 June 2012 (UTC)
The $context parameter is not given enough of a description.
So I've suggested an edit that lifts text from: https://developer.wordpress.org/reference/functions/remove_meta_box/
