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

As someone who actually prefers to use auto-generated thumbnails as much as possible... those auto-generated thumbnails are absolutely terrible a fair chunk of the time. ...I've also seen some pretty awful user-generated ones, but at least that's their choice.
