Hi Mike,
Thanks for this suggestion.

The system checks the session status whilst the ticket reply box is in focus. This will provide an update when another admin is replying to the same ticket, and will also display a message if the session has expired: https://www.dropbox.com/s/l7it59z11sosgwv/Screenshot%202021-12-16%20at%2018.00.13.png?dl=0

It is not desirable to perform the checks when the reply window is out of focus, because this could quickly cause load when multiple staff are online with multiple tabs open each.

The message contents is saved automatically to browser storage, so in the event of session loss, one can navigate back and it will be retained.

What enhancements would you like to see here, so we can scope this change appropriately?
