How does the chat feature work?
The chat feature allows the involved parties to send and receive text-based messages. The chat works in real time; when you see your message on the chat screen, the receiver of the message will be able to see it, too.
When a message has been sent over chat, a blue number will appear on the receiver’s chat window that corresponds with the number of messages the sender sent. If you do not see a response, remind the receiver to check their chat window to view your message.
