What happens when the operating hours end and I still have an active chat?
When the operating hours on Chat ends, the agents status will be set to Invisible. Agents will still be able to continue their current chats. All waiting chats on the queue will remain until either the visitor leaves the chat or the chat is manually served by an agent.
Assigned routing will no longer offer chats to agents once operating hours end so it is best to check the visitor list to see if there are any chats queuing.
