Additional clarification:
No one lost a verification badge today–If you received an email that your channel will no longer be verified, this was just an advanced notice & you can appeal
The checkmark has never appeared on YouTube mobile channel pages (this will be added soon)https://twitter.com/TeamYouTube/status/1174735005215420416 …
The badge was a symbol that YOU gave to people -- taking it away arbitrarily does nothing but alienate your userbase. If you really want to save face, grandfather current recipients. I don't have or even want the badge and it's still frustrating as a creator. C'mon, guys.
