I have built a workout app that uses GPS data to calculate a user's pace and distance. The user will start the app then likely lock their phone while the workout is happening. The app will only receive GPS data when the user's phone is locked if Location Services is set to 'Always'. It does not work when set to 'While Using the App'.Our users would strongly prefer for it to be 'While Using the App' instead. Any tips on what to change in the code to make the 'While Using the App' setting work in the case when the phone is locked?Thank you!
