Is there any way to get the Watch Series 2 to use it's own GPS on a run or walk even when you have your iPhone with you? My iPhone is eating up data on my cellular plan because the Watch defaults to using the iPhone GPS when it is with me instead of using its own GPS. Very annoying and I will have to upgrade my data allowance because of it. I can't find a solution other than manually switching off cellular on the phone, which I don't want to do. Thanks for any suggestions.
