I have 4 Roku's in my house and my Pixel does not see any of them in the Cast screen. My Galaxy Note 5 had no problems with casting. I went and bought a new Chromecast and amazingly it was found by the Pixel right away. This is really unfair, I much prefer my Roku. The Chromecast is fine for casting but, the Roku has so much more content. It seems unfortunately like Google is acting more and more like Apple with their devices. Unless they say Google they don't play nicely with each other. I didn't realize all the functions I was giving up by switching to Pixel.
