TestSubmitFramesWhenNotVisible failing on Unity

I am writing an oculus app and running the oculus validator. It is my understanding that the app needs to stop outputting frames when it looses vr focus: https://developer.oculus.com/documentation/unity/latest/concepts/unity-lifecycle/

However, I am not clear if I am supposed to be doing this manually. From what I can tell on old forum posts, unity is supposed to handle this automatically for me. From what I see, when the the app loses focus, it's mirror window on the computer screen goes black, but the TestSubmitFramesWhenNotVisible fails anyway with 2 frames submitted. Is there some code that I should be calling in my unity scripts in response to OVRManager.hasVrFocus?

I find it interesting though, that the number of ovr_CommitTextureSwapChain goes down from 36 to 2.

    You're better off posting this in the developer's forum mate. There's a drop-down list box at the top of this page on the right that currently should say Community. Click on it and select Developer and it'll take you there.

    I passed it once by disiabling camera, I attached this script to a gameobject in the first scene and dragged the camera from the ovr gameobject into the array for the script.  I then failed again so getting inconsitent results is my new challenge.  Here's a starting point at least.

    using System.Collections;
    using System.Collections.Generic;
    using UnityEngine;

    public class HMDCheck : MonoBehaviour
    {
        public Camera[] cameras;
         // Update is called once per frame
        void Update()
        {
            if (!OVRManager.isHmdPresent)
            {
                foreach (Camera item in cameras)
                {
                    item.enabled = false;
                }
                Time.timeScale = 0f;
                Debug.Log("Freeze");
            }
            else
            {
                foreach(Camera item in cameras)
                {
                    item.enabled = true;
                }
                Time.timeScale = 1f;
                Debug.Log("Unfreeze");
            }
        }
    }
