title: React Native MapBox is not following the blue dot on iOS
body: <p>I'm trying to get MapBox follow the user (blue dot) but it is not following, the dot moves but the camera stays still.</p>
  
  <p>Also tried with Mapbox.UserTrackingModes.Follow</p>
  
  <p>The same code works with Android.</p>
  
  <pre><code>     &lt;Mapbox.MapView
          ref={map =&gt; { this.map = map; }}
  
          styleURL={Mapbox.StyleURL.Light}
          zoomLevel={15}
          centerCoordinate={this.initCenterLocation()}
          onRegionIsChangin={this.updateGeoFire()}
          style={{flex: 1}}
          showUserLocation={true}
          userTrackingMode={Mapbox.UserTrackingModes.FollowWithHeading}
        &gt;
  </code></pre>
