Roku Xfinity Beta does not return to last channel watched
If the TV is turned off (Roku is left ON constantly) while using the Xfinity Beta app I would expect Roku and the Xfinity app to be on the last channel watched when I turn the TV back on (just like a cable box stays on the last channel watched). Instead, when I return later and turn the TV back on, I find Roku is now out of the Xfinity app and back on its home page. I've tested many times and no change so I know it's not a WIFI or internet issue.
I'm using latest Roku Streaming Stick+ on several different TVs and they all do the same thing.
