My UI Buttons work in editor, but not when I export to android (using Cardboard VR)?,My buttons working on editor, but not on android (Gooogle Cardboard VR)

I’m currently working on a VR Game for android, and though I have tried for days to find the solution for this issue, I still can’t figure it out. Therefore, I am here to ask you for help in this matter.

My UI buttons seem to work perfectly in the Editor, but once I export it, they simply refuse to be clicked (doesn’t even highlight). I have absolutley no clue as to what may be causing this, any help would be appericiated.

My Code:

    public void PlayGame()
    {
       SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex + 1);
    }

    public void ExitGame()
    {
        Application.Quit();
        Debug.Log("Game Terminated");
    }

}

Thank you.,I’m working on a VR game, and I’m using google cardboard for it, I’ve got one problem though. My UI buttons work in the editor, but not when I export the project to my phone.

My code:

    public void PlayGame()
    {
        SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex + 
1);
    }

    public void ExitGame()
    {
        Application.Quit();
       Debug.Log("Game Terminated");
    }

My question to you, faithfull helpers on the unity questions, what may be causing this, and what solutions are available?
I’m sincerely gratefull for any help I can get, thank you.

Have you tried using the XR Ray Interactor? (using xr interaction plug-in).

I was having the same issue (but in Oculus quest), I gave up using the UIHelper prefab, so I tried using the XR Ray Interactor prefab, worked perfectly with very easy setup.
