Sharing answers to top q's we’re seeing about the thumbnail experiment: – Custom thumbs aren't going away – 99.7% still see the creator's custom thumbnail – A lot of creators use auto-generated thumbnails, this test helps improve them for those using them: https://goo.gl/A7oDmr
I understand testing as a dev. I was part of the test until today and it annoyed me more than it should because I thought previously viewed videos were new videos until I realized what was happening. Hope you got some valuable data! Thx for my thumbnails back
