The Control Centre staff can send you a message that will appear as a pop up on the top of your screen.
It is important that before you leave from your first stop as well as at the end of the service, you check your notification tab for any messages that may have been sent.
If you need to view a message that was sent to you again, this can also be viewed by selecting the notification section at the bottom of the screen.
This will show all messages received in the past 24 hours and will include the date and time you received them.
