Google play services cloud save not responding

[saqibkhan2523]

The following is the script and I am calling signing functions and OpenSave(bool saving) from another script on button click. Now its not working. I do not know why.

    public static PlayServicesScript instance;
    [SerializeField] Text test_dataText;
    [SerializeField] Text test_dataStatusText;
    void Awake()
    {
        if (instance == null)
        {
            instance = this;
            DontDestroyOnLoad(this.gameObject);
        }
        else
        {
            Destroy(this.gameObject);
        }
        try
        {

            PlayGamesClientConfiguration config = new PlayGamesClientConfiguration.Builder().EnableSavedGames().Build();
            PlayGamesPlatform.InitializeInstance(config);
            PlayGamesPlatform.DebugLogEnabled = true;
            PlayGamesPlatform.Activate();

        }
        catch (Exception exception)
        {
            Debug.Log(exception);
        }
    }
    public void SignIn(Action successCallback = null, Action errorCallback = null)
    {
        try
        {
            Social.localUser.Authenticate((bool success) =>
            {
                if (success)
                {
                    successCallback?.Invoke();
                }
            });
        }
        catch (Exception e)
        {
            Debug.Log(e);
            errorCallback?.Invoke();
        }
    }

Today I opened and ran the app again and it worked. Can anyone tell me why is this? My wifi was connected so no issues there.

Also how can I save a static object on cloud. I am Unable to convert it to byte data.
