After releasing the new Blue $8 monthly subscription service to the US, UK, Canada, Australia and New Zealand only on Saturday without the verified checkmark, Twitter is now rolling out the service to all users on iOS, and those who subscribe are getting verified immediately. The update is available on the iPhone and iPad, but it is unclear when it will come to Android.

Apart from getting the verified checkmark, the other benefits of the new Twitter Blue promised by Elon Musk, such as the ability to post longer videos and see half as many ads are not available yet but listed as “coming soon.” The new Twitter Blue has attracted a lot of criticism from users, especially verified accounts, since Musk announced it will be required to get verified. On Wednesday, Twitter began testing “Official” grey checkmarks on select accounts, which product manager Esther Crawford tweeted is “not available for purchase.” The grey checkmark was designed as an extra layer of authenticity for accounts but only lasted for a few hours before Musk announced, “I just killed it,” in response to YouTuber MKBHD.

After the confusion, Musk tweeted, “Twitter will do lots of dumb things in coming months. We will keep what works & change what doesn’t.” Crawford quoted Musk’s tweet and said, “there are no sacred cows in product at Twitter anymore” and that the company would try a lot of things which might fail in order to find “the right mix of successful changes to ensure the long-term health and growth of the business.”

Twitter Blue used to be a $4.99 monthly service before Musk took over the company. The service came with other benefits, including the ability to edit tweets, but subscribers had no verification option. Musk had initially announced the revamped Twitter Blue would cost $20 monthly but faced a lot of backlash from users, particularly author Stephen King, who helped bring down the service to $8 monthly.
