OVRInput.GetActiveController() == OVRInput.Controller.LTrackedRemote ... Not working in Unity3D

Hi I'm having a little trouble using OVRInput.GetActiveController, perhaps I'm misunderstanding how it's used.
I'm building a Samsung GearVR app which needs to support both IF the player has a SamsungGearVR Controller paired with their phone as well as the condition where they do not. 

What I need to achieve is a branching input scheme dependent on if they have a controller paired. But I'm stuck just trying to determine whether they have the controller paired. The following code is the bare bones test I was trying to do, but if the controller IS paired it never kicks off the ProcessControllerClickAtPosition method.

The other method works fine, I can get the ProcessHMDClickAtPosition to correctly get triggered whenever the touchpad on the HMD is clicked.

I'm forced to use Unity 5.5.4 because my work is being integrated into a larger project of which I can't control so any advice will have to work on that version of Unity I'm afraid.

Any help at all is greatly appreciated!

public class ManualGaze : MonoBehaviour
    {
        // Update is called once per frame
        void Update()
        {
            if (OVRInput.GetActiveController() == OVRInput.Controller.LTrackedRemote || OVRInput.GetActiveController() == OVRInput.Controller.RTrackedRemote)
            {
                // yes, are they touching the touchpad?
                if (OVRInput.Get(OVRInput.Touch.PrimaryTouchpad))
                {
                    // yes, let's require an actual click rather than just a touch.
                    if (OVRInput.Get(OVRInput.Button.PrimaryTouchpad))
                    {
                        // button is depressed, handle the touch.
                        Vector2 touchPosition = OVRInput.Get(OVRInput.Axis2D.PrimaryTouchpad);
                        ProcessControllerClickAtPosition(touchPosition);
                    }
                }
            }
            else if (OVRInput.Get(OVRInput.Touch.PrimaryTouchpad)) // finger on HMD pad?
            {
                // not using controller, same behavior as before.
                Vector2 touchPosition = OVRInput.Get(OVRInput.Axis2D.PrimaryTouchpad);
                ProcessHMDClickAtPosition(touchPosition);
            }
        }

        private void ProcessHMDClickAtPosition(Vector2 touchPosition)
        {
            Debug.Log("Heard that since there is no controller the touchpad was clicked instead!");
        }

        private void ProcessControllerClickAtPosition(Vector2 touchPosition)
        {
            Debug.Log("Heard the touchpad on the controller clicked!");
        }
    }
