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
You can add location information to your Tweets, such as your city or precise location, from the web and via third-party applications. You always have the option to delete your Tweet location history. Learn more
why not just make it display the custom thumbnail until you hover the mouse over it at which point it shows you an auto-generated thumbnail that takes footage from the video so content creators can still personalise their work & viewers can get a preview when they want to see one
