Why the fuck can't I turn this fucking button off? It shows

You can't turn it off because it appears automatically for convenience.

A really solid solution for this problem is to set up your own WiFi network separate from your roommate's. No TV on the new network, no cast button.

Also for what it's worth I just tapped the button on my phone and it still asked whether I meant to connect to my Chromecast. Not sure why yours is automatic.

The TV has a YouTube app built into it and so it auto connects to any other YouTube app on the network. It's different from Chromecast so it doesn't ask at all, it just instantly streams and it's annoying as fuck.

My friend had one of those TVs and I used to have to tap the device name there, too. I guess it varies by model or it's changed since then.

But yeah, we're both on the same page here that the network is the key. Connect via a different device and it'll be invisible to you.

Well, thanks for the tip to set up my own network, I'll get to it one day. But still, Google should at least give an option to users who don't use cast to begin with, is a simple toggle too much to ask?
