My wife and I have the same iPhone6 (set up exactly the same way, same release, location services turned on, etc.) and her phone doesn’t work with the hub properly. Right now, for example, it shows it as “present” although she’s many miles away at work (it didn’t show her leaving this morning). The same is true on either the app on our phones or on the web browser (she’s on my account, with her own login, of course).
Her GPS works (she used it yesterday for walking) and, as I said, everything including location services for the app is turned on. Any ideas why the phone itself isn’t working as a sensor and what I can do about it? (my own phone works great without any issues as a sensor).
