Please see this.

I want to watch certain videos and they are not there. I think you should only not add videos with gory. Other ten that it is a good app. Not as good as the real YouTube. You can not post videos on it like the real YouTube. I wish that you could add videos. Please please update it so that you can add videos to it. Like the read YouTube. Thank you soooo much.
