Why can't I download Netflix on my iPhone 6s Plus?

If your cousin downloaded Netflix before they changed the minimum requirements, then she may still be able to use the app, but it will no longer be updated. That is a change that Netflix has made for users who want to download their app. When a developer changes the minimum iOS requirements, it does not remove the app from the phone if the device is no longer supported.

Netflix has decided to support their app with iOS 17 and later.

iOS 17 requires iPhone XS, iPhone XR, or iPhone SE 2nd, or newer, and is not available for iPhone 6S.

For questions about or assistance with the Netflix app, or its version support, contact Netflix support.

Delete Netflix app from your cousin’s iPhone, and test again.

You’ll find you now have the same everything, neither can download, though now with added cranky cousin.

For feedback on the iOS versions Netflix is supporting, contact Netflix support.
