One of the new features of the Channels ATV beta that was listed in the email I received today was the ability to change channels using the iOS app. How do I do that? Is there an update to the iOS app that adds that ability? Or is there an iOS beta I should be using in conjunction with the ATV app?
This support has been available with the published versions for a while now. In order to get the option to play the channel on your TV, Channels must be open on your Apple TV.
