Trigger logout ‘everywhere’

Hi @bernardberry646 !

This feature is currently not supported.
However, I will add it in v2.1.3 ; in the meantime, you can replace the content of your wp-content/plugins/wp-remote-users-sync/inc/api/class-wprus-api-logout.php files (on every connected sites) with the following (I tested this, but as it is not officially deployed yet, use at your own risks):

<?php

if ( ! defined( 'ABSPATH' ) ) {
	exit; // Exit if accessed directly
}

class Wprus_Api_Logout extends Wprus_Api_Abstract {
