My P3 Advance is having an issue that just started tonight, and I'm unable to find anyone having this same problem. I did upgrade the latest Firmware, and have flown it since the update and everything worked fine. Tonight I powered on the P3 and I'm getting a constant Beep, Beep, Beep and none of the lights on the Prop Arms are illuminating. Has anyone else experienced this? I have tried calling DJI Tech support but after 20 minutes of being on hold it disconnects. Also, I am showing the display from the Camera while the Drone is powered on but unable to do anything else. I thought maybe there was something wrong with the Firmware and attempted to format the SD card in the Drone, but it comes up saying "Format failed" so it won't even let me reformat the Card to attempt an Firmware re-install.
