ParseUser.getcurrentuser() is returning null in Xamarin form using Version 2.0 develop 1

[prakharprakhar89]

client = new ParseClient(App.APPId, App.Server, App.Key,
                new LateInitializedMutableServiceHub { },
   new MetadataMutator
   {
       EnvironmentData = new EnvironmentData { OSVersion = Environment.OSVersion.ToString(), Platform = Device.RuntimePlatform, TimeZone = TimeZoneInfo.Local.StandardName },

       HostManifestData = new HostManifestData { Name = Application.Current.Id.ToString(), Identifier = Assembly.GetCallingAssembly().GetName().Version.ToString(), ShortVersion = Assembly.GetCallingAssembly().GetName().Version.Build.ToString(), Version = Assembly.GetCallingAssembly().GetName().Version.Build.ToString() }
   }



                );
client.Publicize();

client.LogInAsync(UserNameText, UserPasswordText);

Problem when App closed and reopen the app======
ParseUser parseuser = client.GetCurrentUser();
here parseuser is getting null
