Back in October 2018, Netflix stopped letting new users, who had downloaded the Netflix app to their iPhone or iPad, use Apple's native in-app billing system for these devices to pay for their subscription.
With Apple taking 15% - 30% of revenue, Netflix told all new users to render payment method for their streaming service directly on its website. Users who'd already signed up for Netflix through Apple's App Store could keep paying via Apple until they cancelled their subscription, however.
