having problem with multiplayer using photon network

When i join a room to play the game and then if i leave the room during the gameplay i am on the main menu , then i search for a new room to join it's keep searching but when i close the app and open it again it's finding the match and i am able to join but its not happening when i leave and try to join again.here is the function which i am calling on leave button.

public void LeaveGame(bool finishWindow) { if (!iFinished || finishWindow) { PlayerPrefs.SetInt("GamesPlayed", PlayerPrefs.GetInt("GamesPlayed", 1) + 1); PhotonNetwork.BackgroundTimeout = StaticStrings.photonDisconnectTimeoutLong;

         //GameManager.Instance.cueController.removeOnEventCall();
        

         GameManager.Instance.playfabManager.roomOwner = false;
         GameManager.Instance.roomOwner = false;
         GameManager.Instance.resetAllData();
         PhotonNetwork.LeaveRoom();
         SceneManager.LoadScene("MenuScene");

     }
     else
     {
         ShowGameFinishWindow();
     }
 }
