Unable to use the App Store, iTunes Store, or Siri on Apple TV properly? You are not alone. Multiple cloud Apple services seem to be suffering an outage thereby hampering their usability.
Even Apple’s Online Store and iMessage seems to be down for many people. The company has already updated its status page to reflect that its services are facing an outage.
If you are being affected by this outage, there really is not much that you can do except wait for Apple to identify and resolve the issue.
