Cannot get room list inside lobby

I am now implementing the rejoin function, so before I call the ReJoinRoom function,
I need to check the last room is still existed to avoid



In OnConnectedToMaster() callback, I call
PhotonNetwork.JoinLobby(new TypedLobby("GameLobby", LobbyType.SqlLobby));
to enter a named lobby and successfully get lobby information in OnJoinedLobby() callback.

In my Android device, I create a room after join lobby by
PhotonNetwork.CreateRoom(null, new RoomOptions{MaxPlayers = 2, EmptyRoomTtl = 50000, PlayerTtl = 180000, PublishUserId = true}, null);

and ensure the room is available by

PhotonNetwork.room.IsOpen = true;
PhotonNetwork.room.IsVisible = true;

in OnJoinedRoom().

Then at my Unity editor, after joining lobby, I tried to get the room list

RoomInfo[] rooms = PhotonNetwork.GetRoomList();
		foreach(RoomInfo room in rooms){
			Debug.Log("room : " + room.Name);
		}

The room list is always empty, but I can still rejoin it by ReJoinRoom function when the room is still existed.

How to I solve it? Thank you.
