NBC says that if you pay for Peacock Premium, you'll be able to watch shows a day after they air. I just realized that I have been watching them at least a week after, because the shows aren't visible on the app the next day, as advertised. Finally realized it after almost seeing a recap of This Is Us. When I went to watch it, sure enough, there is a new episode. After I watched it, I realized that the bit that I saw of the recap had no part in the show. It was the previous episode.
