Bug 2021.2 EnhancedTouch stopped working on device

After updating from 2021.1 to 2021.2 using version from website (not hub) code below, in particular Enhanced touch bits have stopped working when app is built to device, It still works in game window when running in unity.

Code (CSharp):

1. using UnityEngine;
2. using UnityEngine.UI;
3. using UnityEngine.InputSystem.EnhancedTouch;
4. using Touch = UnityEngine.InputSystem.EnhancedTouch.Touch;
5.  
6.  
7. public class GameUiManager : MonoBehaviour
8. {
9.  
10.  
11.     // Fields
12.     [SerializeField] private GameObject movementStrip;
13.     private Rect movementStripRect;
14.     private float movementMaxValue;
15.     private float movementMinValue;
16.  
17.  
18.     // Lifecycle Methods
19.     private void Start()
20.     {
21.         CreateMovementStripRect();
22.     }
23.  
24.  
25.     private void OnEnable()
26.     {
27.         EnhancedTouchSupport.Enable();
28.     }
29.  
30.  
31.     private void OnDisable()
32.     {
33.         EnhancedTouchSupport.Disable();
34.     }
35.  
36.  
37.     private void Update()
38.     {
39.         HandleMovementStripInteraction();
40.     }
41.  
42.  
43.     private void HandleMovementStripInteraction()
44.     {
45.         if (Touch.activeFingers.Count >= 1)
46.         {
47.             bool isActiveFinger = false;
48.             float movePosition = 0;
49.  
50.             foreach (Finger finger in Touch.activeFingers)
51.             {
52.                 Vector2 fingerPosition = finger.screenPosition;
53.                 if (movementStripRect.Contains(fingerPosition))
54.                 {
55.                     isActiveFinger = true;
56.                     movePosition = fingerPosition.x;
57.                     break;
58.                 }
59.             }
60.  
61.             if (isActiveFinger)
62.             {
63.                 HandlePlayerMovementEvents(movePosition);
64.             }
65.         }
66.     }
67.  
68.  
69.     private void HandlePlayerMovementEvents(float movePosition)
70.     {
71.         float normalizedPosition = Mathf.InverseLerp(movementMinValue, movementMaxValue, movePosition);
72.  
73.         if (normalizedPosition <= 0.25 )
74.         {
75.             GameManager.Instance.SetPlayerPosition(PlayerPosition.Left);
76.         } else if (normalizedPosition <= 0.75 )
77.         {
78.             GameManager.Instance.SetPlayerPosition(PlayerPosition.Middle);
79.         } else if (normalizedPosition <= 1 )
80.         {
81.             GameManager.Instance.SetPlayerPosition(PlayerPosition.Right);
82.         }
83.     }
84.  
85.  
86.     private void CreateMovementStripRect()
87.     {
88.         float scaleFactor = Screen.width / GetComponent<CanvasScaler>().referenceResolution.x;
89.         Transform stripTransform = movementStrip.transform;
90.         RectTransform stripRect = (RectTransform)stripTransform;
91.         movementStripRect = new Rect(
92.             stripTransform.position.x,
93.             stripTransform.position.y,
94.             stripRect.sizeDelta.x * scaleFactor,
95.             stripRect.sizeDelta.y * scaleFactor
96.         );
97.         movementMaxValue = stripTransform.position.x + stripRect.sizeDelta.x * scaleFactor;
98.         movementMinValue = stripTransform.position.x;
99.     }

Sure thing, issue is here
https://fogbugz.unity3d.com/default.asp?1378315

I believe issue id is: 1378315

There are now few additional details I can add

1. Issue occurs on iPhone XS and iPhone 13 Pro (iOS 15)
2. It still remains in latest version (now downloaded from the hub) 2021.2.1
3. Occurs on both "Intel" and "Silicon" versions
4. Other input system touch events that use Player Input and things like On-Screen Button, do work

I'll keep looking into this, but its hard to debug as it does work in editor and there are no errors
