WWW.LoadFromCacheOrDownload not working

Question

I can't figure out why WWW.LoadFromCacheOrDownload is not working. Here is simple script

 using UnityEngine;
 using System.Collections;

 public class Main : MonoBehaviour {

 // Use this for initialization
 void Start () {
     loadAndCreate(null);
 }
 
 // Update is called once per frame
 void Update () {
 
 }
 
 
 public static void loadAndCreate(string _url) {
     Instantiate(WWW.LoadFromCacheOrDownload("https://www.dropbox.com/s/2ap3ixvab2lpqkn/Flame_ios.unity3d?dl=1", 1).assetBundle.mainAsset, new Vector3(0,5,0), Quaternion.identity);
 }
 }

It works absolutely fine in Editor. But when I load application on iPad everything I get is

starting www download: https://www.dropbox.com/s/2ap3ixvab2lpqkn/Flame_ios.unity3d?dl=1

And after this my main thread is halted. Here is the stack trace when paused:

Bad idea to run blocking operations on the main thread. Looks like your WWW call won't return until the asset is fully downloaded and extracted, which will effectively freeze the game until that happens.

Instead, you may want to run the WWW call as a coroutine -- with the "yield" keyword -- or check periodically to see if it has finished. There are plenty of tutorials about this around the net, but here are some links to get you started:
