Google Nest Community

I got it all set the same network but can't get it to connect to watch my apps on TV it shows it's there it won't connect and it factory reset already

Hi, I'm sorry this comes off as weird. All other issues aside. Also I'm trying to do is simply screen share from my pixel to my Chromecast. Do I need Wi-Fi connection? Can't I just share from phone to Chromecast? I've had issues over the past few yea...
