Owners of the new Apple TV 4K, which started arriving on 13 November, are finding that YouTube will not start properly on a fresh box. The fix takes three steps.
Two symptoms are going around. One is a blank screen with a QR code and the line “YouTube is not yet available on this device.” The other is a working app with a translucent red strip along the bottom that says “YouTube app is approved for device testing only and not for production use.”
Tom Warren of The Verge tested the problem on a new unit, and posted the fix that worked. First install tvOS 27.2. Next, restart the box by force, holding the TV button and the back button for five seconds. Finally, delete YouTube and reinstall it.
Warren found that the new software and the restart did not clear it alone on his own unit, even with both steps done correctly. Only reinstalling the app did, so do not stop after the first two steps.
If you are not sure which software the box is running, open Settings, then System, then Software Updates, and install tvOS 27.2 from there. A normal restart lives under Settings, System, Restart, and it is worth trying before the button combination if the box responds at all. The button combination is the harder reset for a box that is stuck.
The new model is the fourth-generation Apple TV 4K, and it is the one that began reaching customers on 13 November. Warren needed the reinstall on top of the system update.
