To date, whether we like it or not, Netflix’s preview videos of movies and TV shows start playing after you log in to your account and there is no way to stop them from playing automatically. Netflix has released a very useful solution to this rather annoying feature in its latest update, ‘auto-play preview videos’. This feature can only be disabled from a computer. The mobile app has yet to be updated with this feature.
