I disabled most of the ATT apps and a bunch of others that I didn't think I would use. They go to the bottom of the ALL app list where you can re-enable them should you decide you need one.
I recently decided to try the remote control app... but couldn't get it to start. So I had to scroll down through the list of disabled apps to find the one that was linked to WatchOn and re-enable it. The remote control works fine now.
