Windows Store app - Joystick not working

I have been trying to get joysticks to work in Windows Store apps. It works fine in the editor.

Here is a screenshot of my player settings:

I read that you only need to enable HID, but I enabled everything for the hell of it.

Here is my code:

using UnityEngine; using System.Collections;

public class JoystickControl : MonoBehaviour {

 float speed = .02f;

 Material mat;

 // Use this for initialization
 void Start () {
     mat = gameObject.GetComponent<Renderer>().material;
 }
 
 // Update is called once per frame
 void Update () {
     mat.color = (Input.GetButton("Fire1")) ? Color.red : Color.white;
     Vector3 moveCube = new Vector3(Input.GetAxisRaw("Horizontal"), 0f, Input.GetAxisRaw("Vertical"));
     transform.position += moveCube * speed;
 }

}

Just a note, the keyboard input (WASD + left mouse click) work in the Windows Store app, it's just the joystick that isn't working.

Is there a setting somewhere that I'm missing that will allow joysticks to work in Windows Store apps?

Thanks!
