Someone has come up with the message "Aircraft not linked to a phone number. Limited Flight Distance. Link Aircraft. Code 3000004" I have never had this message before and then request a phone number valid for China. Please help.
What application are you using when you see this message?
This happens to me on occasion too - general these steps:
1. Clear all cache in Settings.
2. Bring the aircraft to the place with strong GPS signal.
3. Connect your mobile device to local network and reboot the APP.
4. Reconnect aircraft to APP.
