Went from Spotify to YT and have these issues. 1. I press cast, not all devices show up or they pop up and jumble around so hard to click on correct one. 2. Speaker group doesn't show up only individual Nest devices. 2. If already playing on Nest speakers started by voice and then open app it doesn't pick up on what's already playing and starts it's own playback so can't control speaker output. Both things Spotify do perfectly, and you're Google so should work well with your own devices surely?
