Handle Discontinuity
If a client briefly loses connection to Ably, for example when driving through a tunnel, the SDK will attempt to recover the connection. If the disruption lasts for less than 2 minutes, then on reconnection the SDK will automatically reattach to any rooms and replay any missed messages. During periods of discontinuity greater than 2 minutes then you will need to take steps to recover any missed messages, such as by calling history. The Chat SDK provides anonDiscontinuity() handler exposed via the Room object to assist with this:
