Ask HN: Google Discover shows YouTube Ads (despite paid ad-free user)

Recently Google updated what used to be known as Google Now / Google Feed, (now called Google Discover) on Android. For some things like recaps of sports teams I follow, it has now started playing YouTube videos in-line, instead of opening the app. I've noticed it's also started serving 6s ads from here, even though I'm a paying customer of Google Music / YouTube Red, and there doesn't appear to be a way to stop this behavior.

Anyone else seeing this? It's pretty annoying/unfriendly behavior considering I've been paying for years to avoid this kind of thing, and really inexcusable, since the Discover app is part of Google Search and has access to my account info.

I'm not sure if this is a bug or just Google being Google.
