Can you please check now? If still not working please let me know which version of the plugin you are using.

Can you please install a cron plugin (eg. WP Crontrol) and check if cron is firing correctly?

How many users do you have?
This plugin makes a notification request to query new messages every 2 minutes by default. You can change this by using following code

add_filter( 'fep_filter_ajax_notification_interval', function( $interval ){
    $interval = 5 * MINUTE_IN_SECONDS * 1000;
    return $interval;
});

After adding this code, it will make request every 5 minutes (you can change this to any number). Purge all cache and wait some time. Then check.

Those are the settings. Do you have any caching setup? If yes, purge all caching.
If your website is open in some browsers, this call will continue to make until they close the browser or navigate to another page.

You can send email to admin using following code. Change content as you like.

add_action( 'fep_action_message_after_sent', function( $message_id, $message, $new_message ){
	wp_mail('admin@example.com', 'New Message', 'New message waiting for approval' );
}, 10, 3);

Is the message sent to Admin or any user?
