Strangest thing happened to me yesterday. I've been experimenting with using the location function in Reminders on my cellular iPad to remind me of stuff when I arrive at certain locations. I always leave cellular data on and just toggle Wi-Fi on and off as needed. So the other day I was at my house and I turned off Wi-Fi and as soon as I switched onto LTE, immediately a reminder popped up that was set to go off the next time I arrived at my friend's house. But my friend lives 2 miles away from me! What on earth could cause this behavior? I checked the properties of the reminder and I had the location radius set at 328 feet, so it definitely shouldn't have been triggered 2 miles away. And under Privacy, I have allowed the Reminders app to use my location. Doesn't seem like a very reliable feature.
