Smartphone: I get the message "Failed to start Companion mode. Please turn on Wi-Fi and check that you are connected to the same network (LAN) as the main device."

Check your devices’ network connection status and Firewall settings.

If Companion mode fails to start for any of the following reasons, please refer here.
