They Broke It
Update: The does not function properly on devices running iOS 10.3.2. Programs play back for 1-2 seconds, restart at the beginning of the program, and continue this cycle indefinitely.
This worked well most of the time, until the last update. Now in-home playback of recorded shows frequently returns an "8001 Error", whatever that is. And refuses to play back any recorded shows on any mobile device. Oddly, playback is possible through the XFinity website through a laptop, but that really defeats the purpose of having an app.
