Broke my screen on my iPad Mini 2 Cellular/LTE and I'm going to get an iPad mini 4, and I was wondering if anyone knows, from experience, on whether the cellular/lte is necessary to use the Follow Me function. I know with the phantom it was necessary because the phantoms controller didn't have GPS, but since the Mavic controller DOES have GPS, is the cellular model still a requirement? I called DJI tech support, and they said NO, it is not necessary, but the woman I spoke to didn't seem like she was very experienced. Ive read a lot of posts where there has been different opininons, but they are ALL OVER THE PLACE with their responses. Anyone care to chime in?
