Creator features like live streams, custom URLs, scheduled uploads (and many others!) are not going away with the YouTube Partner Program update. We just updated our Help Center to clearly outline this info (thanks for the suggestion!): https://goo.gl/mAUaMj https://twitter.com/paragraph_8/status/953663437065936897 …
So here's a question I have, I heard we lose custom thumbnails... is that true that you're goin to take away something that channels need and have had this whole time thus further hurting their channel and making is less likely people will check out your video?
