My Galaxy Note 10.1 2014 edition will not show the YouTube Buttons while in full screen on a video,

When I am in full screen on a video, the play button, cast button, exit full screen button, video time bar, back to search button, and finally setting buttons. This only happens in full screen. Thanks for your time!

That's pretty normal I think. You just have to tap the screen once for the buttons to show up again.
