@TeamYouTube I get notification recommendations to "Watch on TV" using my chromecast. I like the recommendations, but I don't necessarily want to watch it on TV. Will disabling disable all recommendation notifications, or just the "Watch on TV"?
This was the wrong answer, but it did help me to find the correct answer. I don't want to turn off Recommended videos, I want to turn off Watch on TV, which is a different option. If I followed your answer I'd have the opposite of what I wanted.
