+1 Same.

So long as the plugin is active on both blogs, switch_to_blog & do_shortcode will generate the form. But I can’t validate/submit the form.

Did you ever figure this out?

A little more digging show that this does work for Multisite. It just doesn’t work for Superadmins.

I can confirm this isn’t working on Multisite. It doesn’t remove the Appearance > Customize submenu item.

You can put this in your theme(s) tho:

function disable_the_customizer () {
    global $submenu;
    unset($submenu['themes.php'][6]);
}
add_action('admin_menu', 'disable_the_customizer');
