Summarize the following:
It's the black icon with an Apple logo and the word "TV" inside. If you've upgraded to iOS 13 or later, you should find the app on one of your home screens. If you don't see it, download it from the App Store. Connecting to a Wi-Fi network is recommended, as downloading videos uses a lot of data. It's the TV icon at the bottom-left corner of the screen. There are several ways to navigate: Tiles for various categories (Movies, TV Shows, Kids, etc.) appear at the top of the screen. Tap a category to do some exploring. Scroll down on the Watch Now screen to see suggestions, additional categories, networks, and promoted content from Apple. Tap Search at the bottom-right corner of the screen to search for a specific movie or show. This displays information about the movie or show, including its ratings, episodes (if applicable), and often a free trailer. If you selected a show with multiple seasons, tap the Season drop-down menu at the top-left corner to browse episodes by season, then tap an episode to see its price and viewing options. Depending on the movie or show, you may see both Buy and Rent options. Rent will always be cheaper, as you'll only be able to watch the video for 30 days. Tap the desired price when you're ready. Once you've confirmed your identity, the selected episode or movie will be purchased and ready to watch. If you don't have a payment method (e.g., a credit card) associated with your Apple ID, you'll need to enter payment information here before the movie or show will download. This displays a list of all content you've rented or purchased using this Apple ID, including the episode or movie you just bought. This saves the movie or episode to your iPad so you won't have to stream it over the internet. Once it's downloaded, you can tap the Play button (the sideways triangle) to watch it.
Open the Apple TV app. Tap Watch Now. Browse for a movie or show. Tap a movie or show. Tap the price to buy or rent. Enter your Apple ID password or use Touch ID. Tap Library once the download is complete. Tap the cloud icon to download the video.
