When shared, the movie or TV show artwork in question will be visible in a layout which can then be customized with other options like polls and questions. When your followers who use Netflix view your story, they will see a "watch on Netflix" link that when clicked will lead them to the app.
“We’re always on the lookout for ways to make it easier for members to share the Netflix titles they’re obsessing about and help them discover something new to watch,” Netflix told TechCrunch.
Netflix's sharing tool is currently only available on its iOS app, but will be rolled out to Android soon. Updates to follow.
