Youtube may limit access to 4K videos only for Premium users
A standard YouTube Premium plan costs $11.99 in the US and includes ad-free videos, background playback, and the ability to download videos for offline viewing. The platform recently said it is testing a new feature in its mobile app with its Premium subscribers that allows them to zoom in on any video. The latest opt-in experimental feature enables a pinch-to-zoom gesture for videos -- and it works both in portrait and full-screen landscape view.
