How to use the ‘Watch Now’ and ‘For All of You’ features in tvOS 15

tvOS 15.x sports. “Watch Now” feature that allows you to get recommendations customized just for you or users — depending on the number of users you’ve added to Apple TV. “For All of You” recommendations take into account each user’s individual taste and viewing history to find something that works for everyone, according to Apple.

Movies and shows shared from the Messages app on an iPhone, iPad or Mac also appear in Watch Now. You can watch Shared with You items on Apple TV, then respond to senders using the Messages app on an iPhone, iPad or Mac.

To set up For You, For Both of You, or For All of You recommendations:

° Open the Apple TV app on Apple TV.

° Navigate down to the For You row, then select the Set Up button in the top-right corner of the row.

° Select one or more user profiles to add or remove.
If a user doesn’t appear, select Add Users to Apple TV, then follow the on-screen instructions.

° When you’ve finished, select OK.

When anyone sends you movie and show recommendations in the Messages app, their recommendations appear in Watch Now in the Apple TV app.
