I just noticed that in the last few weeks this function has used over 700 mb of data. Does anyone know which apps cause this? I frequently use Waze and recently downloaded Automatic Pro and Agenda: Widget +. All three use some GPS or location data, but the phones Cellular use by app indicates minimal data usage. What else could be causing so much Time & Location usage? I'm not ready to blame IOS 10 but am curious if anyone has noticed this. Thanks.
