Question TouchScreenKeyboard.Open() not working after Asset API update

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using TMPro;
5.  
6. public class ShowKeyboard : MonoBehaviour
7. {
8.     private TouchScreenKeyboard overlayKeyboard;
9.     private string inputText = "";
10.     public GameObject inputBox;
11.     // Start is called before the first frame update
12.     void Start()
13.     {
14.         overlayKeyboard = TouchScreenKeyboard.Open("", TouchScreenKeyboardType.Default);
15.     }
16.  
17.     // Update is called once per frame
18.     public void Update()
19.     {
20.         if(overlayKeyboard != null)
21.         {
22.             inputText = overlayKeyboard.text;
23.             inputBox.GetComponent<TextMeshProUGUI>().text = inputText;
24.         }
25.     }
26. }

I have the OVR Manager script on my XRRig with the "Requires System Keyboard" checked and on my input field, I have the ShowKeyboard script - code can be seen above and an onSelect() on the input field calling the ShowKeyboard.Update().
This is the code I used and it worked yesterday but since I did the Asset API Update today it will not show the keyboard in my VR environment. Can anyone help me either revert the Asset API update or help find a way for the code to work with the current update.

 

I've recently tried to implement the overlay keyboard like this and I am also not able to get it working. Using V40. I also used the provided UI demo scene and I am not able to get the keyboard pop up on standalone quest and in the editor.
