I’m on the fence regarding the latest Apple TV and new iOS and need to have a question answered that might get me to do it. To add paying sites like Peacock, HBO Max,Paramount+ with Showtime, Hulu, to up next, do I have to subscribe to them via Apple in order for them to show up in Up Next? At the moment my subscriptions are via scattered sources. There would be a lot said to have all pay apps in one spot for billing. For free sites like Pluto and Tubi, can those be added to up next?
