I was able to add Pandora to background when watching a receiver channel, now I can listen to it from the app. but can't watch the channel, when I try it says if I want to stay with with it or go off of it, if I say stay it goes back to the app. if I say stop it stops and goes to channel with channel sound. I might have created the problem by pressing switch to TV control button the last time I was on it. I tried signing off and on to Pandora, red button reset, no luck. Is there a way to make it work again?
