This system notification means that LaMetric is connecting to Wi-Fi network. Just wait a few seconds. The connection will be restored.
If you see it frequently this means your LaMetric Time device is too far from the router, the Wi-Fi signal is too weak or something (some other devices) may be interrupting it. You need to move your device to another place.
