@YTCreators Is there any way I am able to stop the autogenerated thumbnail experiment? If not how long will this last? It has been very annoying over the past few weeks to no burnt able to see the custom thumbnails.
Thanks for reaching out. While we can't take you off, note that only 0.3% of viewers will see an auto-generated thumbnail and the other 99.7% still see your custom thumbnail. The experiment should end in a few weeks: https://goo.gl/A7oDmr
