Does anyone know why the distance for my parrot won't show on my ipad mini 4th gen. It displays height and all other info except distance. it just shows a question mark. I've reinstalled the software on my ipad and reset the drone but still no change. it use to work but then stopped. The information will show up on my iphone and my air 2 just not the mini. has anyone had this problem or any idea why just that bit of info is not registering. thanks
