I have a new Apple TV that I set to never sleep, but several times now it's decided to go to sleep anyway at some point. It has overnight each of the last two nights, for example. It's also set to not control/be controlled by the TV, so it shouldn't be a matter of sleeping when the TV goes off. Rebooting hasn't changed the behavior. Has anyone else seen this or have suggestions as to how to fix it? I have a second new Apple TV in the other room and it's stayed awake without any problems.
