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 …
Is this confirmation that your prior verification procedures were flawed such that you can produce hard data that demonstrates how a vast number of channels that are currently verified should not have been so?
