You must enable these iOS settings. Open the tracked iOS device. Go to Settings -> FollowMee and make sure the following settings.
- Location: always
- Motion & Fitness: enable
- Background App Refresh: enable
- Use Cellular Data: enable
Location service must be set to "always". Otherwise the app will fail. To alert you when this setting is disabled, enable option "Email me when location service or other critical setting is disabled in tracked device" on
your account page.
