@TeamYouTube after the latest interface update of your app on my PS4, when I press triangle while playing a video, the search dialog comes up and the whole app freezes forever forcing me to close it and start it again. Is this a known issue or am I the only one? 
That's odd, please send a feedback report directly from YouTube with these steps: https://goo.gl/Z9Su3f . While every individual report may not get a direct response, we do review everything and use the details to investigate and fix issues.
