I have a Mavic Air and my video is spotty at best on my iPhone. I fly with my son and he always has a video. I had a iPhone 7 and had the same problem, now I have an iPhone XR and the same thing happens, the video barely shows up on my phone which is connected to the controller. I have sprint service if that does or doesn’t make a difference. I am never near and magnetic sources either. Any help would be greatly appreciated
