The Full-Screen option diverts back to normal screen automatically after end of each part of episodes without my changing it back. It did not use to do this before YouTube made some changes. I want the Full-Screen option to remain on as long as I don't change it back, as it used to. What do I need to do to reset it, or change the default to where the Full-Screen option will remain until I change it. Thank you!
