Apple TV does not update automatically even when set to do so.

Thanks for the help. However this is my third version of the Apple TV. I have always had Auto Update enabled on all of my units. They are always plugged in and connected. I can access them at the touch of the Apple TV Remote. I understand the Auto Update philosophy of it not doing it right away I inquired about that when I di not get an update for my phone. If you are saying that Auto Update only works when I am using the Apple TV like using one of the Apps from the Menu, that is a different story. I normally use DTV and when I want to stream something from Apple TV I switch to that device and stream it. What I have experienced is that when I have an issue and I am given a direction to make sure my SW versions are current and it involves Apple TV it is out of date. Sorry to say but it appears to me that the Apple TV App is not auto updating even if it is turned on. Like I said above when I update it it is because I am working on an issue and see it is not current, I update and keep working on the issue or the issue is solved. I am assuming that your reference to "Long Time" is months and not longer. Thanks for your feedback.
