If you lost a Connection you'd been talking to and it felt like a glitch (for instance, they disappeared without the 'X disconnected from you' notification), then please:
Pull down the Connections page to refresh.
If the Connection hasn't reappeared, you can contact our Support Team by tapping on the Messenger Launcher bottom right.
Be sure to tell us the username of the person you're hoping to reconnect with, and the approximate date they disappeared.
However, if we see that the other person was the one to disconnect, we won't be able to restore the Connection.
