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

I may only watch the videos but even I know nobody wants that we want to see what the creators set up since some of them go out of their way to place very specific thumbnails to get their viewers interest its fun and unique.
