Photon Network instantiate problem when Master changes

Hi,

I'm using PhotonNetwork with Unity v2018.3.10f1.

I've created a "waiting room" to wait for the players to join a room before starting the game.

What I need is that when a player/s is waiting for others, if a player gets into the room, instantiate a prefab on every player in the room, and if he leaves the room, delete the prefab on every player.

First, it works perfectly, the player is instantiated on every player that is already in the room and is deleted when he leaves the room. But when is the Master Client who leaves the room, and rejoins it, is not working anymore and the player is not instantiated on any of the Photon players, nor on his scene.

• How can I do to call the RPC method that instantiate the new player when the Master changes?

Code:

 public void OnSceneFinishedLoading(Scene scene, LoadSceneMode mode)
 {
      if (PV == null)
      {
           PV = GetComponent<PhotonView>();
      }
         
      if (PhotonNetwork.IsMasterClient)
      {
           Debug.Log("Creating lobbyPlayer");
           PV.RPC("RPC_CreateLobbyPlayer", RpcTarget.AllBuffered);
      }
 }
         
 [PunRPC]
 private void RPC_CreateLobbyPlayer()
 {
      PhotonNetwork.Instantiate(lobbyPlayerPrefab, Vector3.zero, Quaternion.identity, 0);
 }

Thanks!
