Sending Messages to Devices
You can use the Deep Freeze Cloud Console to send messages to devices. Such messages are displayed as push messages. Messages are not cached, however; if a recipient computer is powered down or no user is logged in when the message is received, the message will not appear on that computer.
Note that the devices receiving a given message must be all of the same type (iOS, Android, or Chromebook). Chromebooks can only receive messages if they have the Deep Freeze MDM Chromebook Extension installed; see Installing the Deep Freeze Chrome MDM Extension for more information.
  
1.	Go to MDM > Devices. 
2.	Click the iOS, Android, or Chromebook icon. 
3.	Use the checkboxes to select one or more devices. 
4.	Select Message.
5.	Enter the message. 
6.	Click Send.
