Phantom 4 Advanced remote controller connection error

[Saku]

So I have p4 advanced. When I start the djigo4 app on my phone and sign up it immediately changes the aircraft to p4 and says rc connected, even if I haven't even connected it with the cable. When I connect it with usb-cable and put rc and aircraft on it says "enter device" instead of "Go fly". When I press enter device it says remote controller connection error. So the question is how can I get Go fly button?
I have tried
- 2 Different phones
- Usb debug on and off
- 2 Different accounts (With new account it didn't change it to p4 at first but once I connected it with cable it says rc connected and enter device thing and keeps that even if I unplug cable)
- Clear app memory
- Install app again
- Connect phone directly to aircraft with cable

Try a different cable. Make sure it transfers data.
