Also, Chromecast (Ultra) now shows a YouTube app when casting to it. This app puts recommendations on the screen. Even with premium, ads will show when I select one to watch. There's an option to sign in, but if I select it, it just says I can't sign in. Also, with chromecast, it's really annoying that they allow multiple users to put videos in the queue, but only have my videos be ad free. It effectively removes the multiphone feature because I have to look up and play (and ruin my recommendations) on my phone anyways. One premium users being connected should be enough to kill all of the ads. I've also had ads rarely and randomly show up. If I had to guess, some "is this user premium" server was down, and it decided to default to "no", despite that being the explicitly frustrating experience for paying users.
