I think you're right. I have all my stuff connected to Wifi. While the app always finds the CoStar, I don't always get the buttons to control what they should. I have a Vizio TV, a Tivo and a CoStar. Pushing pause on the app works, but when I push play, nothing happens. Channel up work,s but channel down does not work. Recall takes me to the previous channel, but pushing it again does nothing. Etc....
