c# - (New Firebase Unity SDK) Calling GetValueAsync on a Query wont fire its ContinueWith the first time its called

I am building a highscore in my game using the new Firebase Unity SDK but I've run into some problems while trying to update my highscore-list. This is the code Im running when trying to update my highscore list.

public void GetHighscore(Action<DataSnapshot> callback) {
    highscoreRef.OrderByChild("total_score").LimitToLast(10).GetValueAsync().ContinueWith(task => {
        if (task.IsFaulted) {
            // Handle the error...
            Debug.Log(task.Exception.Message);
        }
        else if (task.IsCompleted) {
            callback(task.Result);
        }
    });
}

The first time GetHighscore gets called it will never enter the lambda function inside ContinueWith. However, the second time I call it, it will enter the lambda function and work as expected.

What am I doing wrong here?
