U# Script

using UdonSharp;

using UnityEngine;

using VRC.SDKBase;

using VRC.Udon;

public class TestPlayerJoined : UdonSharpBehaviour

{

public override void OnPlayerJoined(VRCPlayerApi player)

{

Debug.LogWarning("UDON Player " + player.displayName + " has Joined");

}

public override void OnPlayerLeft(VRCPlayerApi player)

{

Debug.LogWarning("UDON Player " + player.displayName + " has Left");

}

}

On live, I can see the above logged in the console when a player has joined or left

On 936, nothing is logged in the console, indicating that these events where never received by my UdonBehaviour
