Hi there,
I have a problem with the code of Remote config.
My WORKING CODE with 3.3.2 is:

 public static bool Maintenance;
    public static string EstimatedQuequeTime;
    public static string StartingTimeMaintenance;
    public static string DownloadStuffs;
    public static string EstimatedMaintenanceTime;
    public static bool ShowEndSeason;
    private struct userAttributes { }
    private struct appAttributes { }

    [System.Obsolete]
    void Awake()
    {
        //Start Updating Remote
        UpdateRemote();
    }

    [System.Obsolete]
    public void UpdateRemote()
    {
        //Start updating game files
        ConfigManager.FetchCompleted += ApplyRemoteChanges;
        ConfigManager.FetchConfigs<userAttributes, appAttributes>(new userAttributes(), new appAttributes());
    }

    [System.Obsolete]
    private void ApplyRemoteChanges(ConfigResponse configResponse)
    {
        switch(configResponse.requestOrigin)
        {
            case ConfigOrigin.Default:
                //No settings modified
            case ConfigOrigin.Cached:
                //No settings modified, loading from cache.
            case ConfigOrigin.Remote:
                //MODIFIED SETTINGS! Load new values...
                SetSettings();
            break;
        }
    }

    [System.Obsolete]
    void SetSettings()
    {
        Maintenance = ConfigManager.appConfig.GetBool("MaintenanceMode");
        EstimatedQuequeTime = ConfigManager.appConfig.GetString("EstimatedQuequeTime");
        StartingTimeMaintenance = ConfigManager.appConfig.GetString("StartingTimeMaintenance");
        DownloadStuffs = ConfigManager.appConfig.GetString("DownloadStuffs");
        ShowEndSeason = ConfigManager.appConfig.GetBool("ShowEndSeason");
        EstimatedMaintenanceTime = ConfigManager.appConfig.GetString("EstimatedMaintenanceTime");
    }

Now with remote config 4.1.1 (after updating from 3.3.2) I have an unspecified error message, I search in every corner of the internet and also today I don’t find a solution, here’s the error message:

Assets\Scripts\General\Remote.cs(34,37): error CS0246: The type or namespace name 'ConfigResponse' could not be found (are you missing a using directive or an assembly reference?)

please send help
