Elon Musk told a YouTuber who noticed his new gray checkmark disappear that he had 'killed it."
But a Twitter product manager clarified that the gray tag would still be rolling out.
Not long after the new gray checkmarks started rolling out to many Twitter accounts on Wednesday, they began disappearing from some accounts.
Elon Musk, Twitter's new owner, responded "I just killed it," to a tweet from Youtuber and tech reviewer Marques Brownlee, who had seen his own gray checkmark disappear.
Musk has said that the new Twitter Blue would cost $7.99 per month, and include the blue checkmark and other features.
