When I watch a video and want to exit, I press the back button but unfortunately I get a loading screen. I have to press the back button again to get out of it and to show me the main menu with the other videos.
When I'm watching a video, video suggestions don't work. Once I select the option by double-clicking down, a loading screen is displayed and if I go back, I return to the main YouTube menu but the sound of the video is heard in the background.
When I watch a video, I can't access its channel. The dedicated button for this option does not work. When I press, the screen turns black for a second and returns to the video.
