We are running a small experiment where 0.3% of viewers will see an auto-generated thumbnail, instead of your custom thumbnail. We are not removing the ability to create your custom thumbnail, but we hope to gain insights on auto-generated thumbnails for the future.

Please reconsider this. Creators love custom thumbnails because they can give the viewers good impressions of the contents of the video. Many creators (including me) doubt that auto-generated thumbnails will be able to do that job as well.
