Mavic Air won't reconnect with iPhone and controller. I clipped a crepe myrtle, tearing one of the blades and dropping about four feet to the ground. When I retrieved the unit the controls told me to recalibrate the compass and IMU, later dropping the request to recalibrate the IMU. I had one "Go Fly" connection since then but now, nothing. I have gone into the DJI Go 4 app and tried reconnecting both wired and Wi-Fi to no avail. Ideas?
