Hi Team,
In your current Symantec version (14.2 RU1) there is no option to display a notification only to blocked devices.
If we enable the existing feature, it will display the notification for both allowed and blocked devices.
And also it will keep popping up each and every time same device plugged in ( I believe this should not be the way)
Please address the above two concern in your next version
Regards
