I’m about to own 2 Chromecast ultra‘s, one came with my Stadia and the other that was store-bought. Can I use one stadia controller to switch between my two Chromecast ultra‘s or will I need one stadia controller for each Chromecast ultra?
Like codesplice said. You know that period of time when you turn on the controller where the light is just blinking for a few seconds, before it vibrates and activates your chromecast? That's the window of time they've left there for you to interrupt the connection to the default chromecast it is about to connect to and enter in the link code to point it in another direction.
