This is happening quite often that I stopped using the 4th gen Apple TV and went back to my Roku 2 (2015). I was watching supernatural the other day and it froze Spoiler: Supernatural S5 E2 Where it showed Bobby in the wheelchair when Dean and Sam were talking. I though it was kind of weird that there was no movement. I was able to get it to work again by rolling it back a bit or reload the program. It has happened with movies too. Also a few times when it shrunk the credits and tried to get them full screen the app froze.
