Hello @TeamYouTube , I would like to know, why are not the thumbnails of the videos on my channel? What happens is that all my videos had thumbnails, and now they are no longer seen.pic.twitter.com/10DKNkIopT

Two question, to YouTube. First, what is the purpose of auto-generated thumbnails? Second, why isn't this an opt-in experiment? No one gets mad if they choose to participate, but when you mess with content they've made, it can rub people the wrong way.
