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
So somehow 0.3% of viewers will see auto-generated thumbnails & the other 99.7% will see the custom one? Maybe I'm missing something but wouldn't you get better feedback if it was 50%? Also why can't auto-generated thumbnails just be an option instead of this experiment?
