WWW not working to load image on iOS from google static maps.

I am trying to load google static map as a texture to a plane in Unity 5.2, and well I can't! The following code works in the editor and OSX but loads the "?" texture in iOS. I tried solutions suggested for ATC here: https://ste.vn/2015/06/10/configuring-app-transport-security-ios-9-osx-10-11/ and it didn't work. below is my code:

 private string url = "https://maps.googleapis.com/maps/api/staticmap?center=34.014717,%20-118.418414&zoom=15&size=640x640&scale=2&maptype=roadmap";

 IEnumerator Start() {
     // Start a download of the given URL
     WWW www = new WWW(url);

     // Wait for download to complete
     yield return www;

     // assign texture
     Renderer renderer = GetComponent<Renderer>();
     renderer.material.mainTexture = www.textureNonReadable;
 }
