react-native-background-geolocation: Not getting data in killed moving state on iOS on any real-device.

Your Environment

Plugin version: react-native-background-geolocation": “3.9.3” & react-native-background-fetch": “3.0.6” Platform: iOS only OS version: 13.1.1,14.3 Device manufacturer / model: iPhone Xr and iPhone 12mini

React Native version (react-native -v): 0.62.2

export const configureBackgroundGeoLocation = () => {
  BackgroundGeolocation.ready(
    {
      desiredAccuracy: BackgroundGeolocation.DESIRED_ACCURACY_HIGH,
      distanceFilter: stores.locationStore.fetchRadius || 10, //distance required for getting location update        // Activity Recognition
      stopTimeout: 5, //this is a timer which runs when plugin eneter into it's stationary state
      disableStopDetection: false, // this is not recommended because will NEVER disable location service until we call background geo location stop

      // Application config
      debug: false, // <-- enable this hear sounds for background-geolocation life-cycle.
      logLevel: BackgroundGeolocation.LOG_LEVEL_VERBOSE,
      stopOnTerminate: false, // <-- Allow the background-service to continue tracking when user closes the app and required for Headless JS ( android killing state)

      startOnBoot: true, // <-- Auto start tracking when device is powered-up.

      preventSuspend: true, //required for heartbeat event for ios,keep your iOS app running indefinitely in the background and prevent the app to going to suspend mode

      //android options

      // With Headless JS, you can continue to respond to BackgroundGeolocation events after your android app has been terminated (assuming you've configured stopOnTerminate: false). but there is no headless mode in iOS

  /**
   *1. calls a function whenever there is an update in location(update depends on distanceFilter=radius(coming from server))
   *2. will be always get called for at least one time, even if there is no movement
   *3.  Will be fired for each recorded location
   */

  BackgroundGeolocation.on('location', location => {
    console.log('on location:', location);
    location && getLocationInputAndSave(location);
  });

// In Android, there is headless mode where we can receive different events like 'heartbeat', 'location' when our app is terminated. This is not available in android.

let BackgroundGeolocationHeadlessTask = async event => {
  let location = event.params;

  switch (event.name) {
    case 'location':
      console.log('on location in killed state:', location);
      location && getLocationInputAndSave(location);
  }
};

BackgroundGeolocation.registerHeadlessTask(BackgroundGeolocationHeadlessTask);

## Expected Behavior
I should receive location updates in the killed state on a real iOS device.

## Actual Behavior
I'm not getting location updates in the killed state on a real iOS device even after moving around 3-4kms. Although I'm getting it on in the simulator using "City-run".
