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 …
This is dumb. No one wanted this change. Even then, the people who are verified right now could keep it like that and the so called celebs could have just received a different color for their verification check.
