A:Answer Yes, the built-in Firestick app allows you to access Discovery +. Of course, it is a subscription service. The first 7 days are free, so you can see if you like it. After that, it is $4.99/mo with commercials or $6.99/mo without. I subscribed to the commercial-free version. It is my first experience with streaming and even I was able to do it, so it was easy enough! Love Discovery +! If you already have a Discovery + subscription, you can just log in on your new TV.
