Google has announced that the YouTube app will cease to function starting in May for iOS devices running an OS older than iOS 7 — this likely refers to the older Apple-developed YouTube app that was discontinued in iOS 6. The change also impacts second-generation and older Apple TV units, which won’t be able to access YouTube starting in May unless Apple chooses to provide a software update for the older model. Users of the YouTube app on these older devices are already seeing a video notifying them of the change, but the app is still functional for now. In early May, users will only see the notification video, and will be unable to access any video content through the app. Google’s support page has directed users of older iOS versions to visit YouTube’s mobile site to view videos. Notably, Google’s official YouTube app for iOS remains listed as compatible with “iOS 6.0 or later”, so it’s unclear why iOS 6 users may be unable to access YouTube unless Google simply plans to drop iOS 6 support in the native iOS app.
