Downloaded title says 'Expired'
TV shows and movies downloaded on your device will expire after a certain amount of time. You can watch a download as many times as you’d like before it expires.
If a download on your device has expired, follow these steps to renew it.
TV shows and movies that are no longer available on Netflix can't be renewed or downloaded again.
Note:Some TV shows and movies have a limit to the number of times they can be downloaded or renewed due to studio and license agreements. If you get an error that says you can't download a TV show or movie again, you'll need to watch it while connected to the internet.
