Sounds like you have a generation 1 Chromecast™ and bad WiFi. We hope you'll try YouTube TV again with a Chromecast Ultra™ and a Nest Wifi™ 3 pack. Take care!
Please tell me this is a parody of the support responses?
The ™s make me lean in that direction.
Asking someone to spend $400+ just to upgrade equipment in order to support a service that doesn’t work well on the original equipment you sold them, takes some guts.
It's sarcasm
I have every generation and type of Chromecast and they all do this same shit and have been doing it since I got YTV two years ago.
