Greetings, PV2+ has been sidelined for 4 years. I have one battery that holds a charge for about 3 minutes. I have full control of propulsion, but no video. I can access and control gimbal but video is blank just shows turning circle on iPad. And "not connected to phantom" on updated iPhone 11pro Max. See attached (indoor screen shot). Getting ready to sell the drone, but don't want to sell it in non-working order. If I can get the video to work, I'll get a replacement battery before selling it. Troubleshooting tips welcomed.
Thanks.
Thanks.
