I just received a notice from my Cellular provider that I had reached my 3GB limit for the month and that overage charges were going to start. I examined my iPad and I found that "Time & Location" services had accounted for a MAJOR portion of the usage. Is there any way to isolate what application has been responsible for all of this activity? The regular list of cellular usage data doesn't seem to provide a clue. For starters, I have disabled location services for almost every application on my iPad and will only re-enable them one-by-one as needed. In some 5 years of iPad usage, this is the first time I have seen anything like this. I have tried to think about any new apps that I may have installed recently and can't think of what it might be.
