Watch a whole movie series in order
Movies that belong together, like Harry Potter or John Wick, are grouped into a collection. That keeps the Movies list short and puts every film in the right order.
1Find the collection
Open Movies. A collection looks like any other poster, but its name ends in Collection.
2Open it
Click the collection. You'll see every movie in it, oldest first. Click a movie to watch it, or press Play to watch them all in a row.
A movie that was just added may show up on its own until the next day. Then it joins its collection.
