I can't speak on the PS4 youtube app since I don't have one, but damn the Xbox One and Wii U Youtube apps are inexcusable. They freeze up constantly (especially the Wii U version which if you try to close the app when it freezes your whole console gets frozen), the connection is always shit, and the Xbox version constantly shows in the lowest resolution for me. Why can the Wii U Youtube app show videos in HD but the Xbox One version can't? I guess its a fair trade off since the Wii U youtube app routinely just says fuck it and stop playing the video with no warning. You would think they would have some sort of "select your video quality" option but no there is none. They are barebone apps that barely function and you would think by 2016, in the fourth year of the Wii U's life and the third year of the Xbox One's life that they would get the Youtube app to function like the desktop and mobile counterparts.
