Add points to an exisiting route -> route invisble. Short move from user required

Hello

I want to track the user's location on a map. So I use

var route = {
   name:"your route",
   points:points,
   color:"blue",
  width:4
};
mapView.addRoute(route);

On every location change I just want to add the current location of the user.

route.points.push({latitude:e.coords.latitude,longitude:e.coords.longitude});

The content of the array is correct -> the new point is added properly, but the user can't see the route. He has to move the map shortly to view the route. There is a possibility to set regionFit to false and after 500ms again to true, but I don't think, it's a good solution, because the map automatically zooms and old iPhones will take more time than the iPhone 4.

Would be great, if someone knows how to fix it!

Thanks

Felix
