Removing meta boxes from post edit screens

I found an old thread with a code snippet showing how to hide the meta boxes, if like me, you like to de-clutter the admin screens for clients. This code no longer works though, so I’ve updated it, and sharing it below in case anyone searches for a solution:

function remove_share_box() {
	remove_meta_box('A2A_SHARE_SAVE_meta', 'post', 'side');
	remove_meta_box('A2A_SHARE_SAVE_meta', 'page', 'side');
}
add_action( 'add_meta_boxes' , 'remove_share_box', 40 );

Note the change of location from ‘advanced’ to ‘side’ that prevented the old snippet from working. I also added a line to remove from posts, not just pages.

H/T to @konsument on the old thread
