AWFUL. it used to work. It won't see my phone and visa versa. I've rebooted the phone, the WiFi , uninstall and reinstall app and factory reset chrome cast!!!! What the hell! I use this as my way to watch TV. Now it won't work! The screen on TV says Ready to Cast. But when I try I get a message not in same network. I only have ONE network! It used to work 2 days ago on this phone. 😡 So I finally got it to work. And then it woukd not plat next video...same reason. I'm ditching the chrome cast.
