There were two issues. One was Safari auto-polling, and that was 3 million users and we don't expect to get those users back. The other issue that was more complex was an encryption issue related to the Twitter integration into iOS, such that when users integrated, a lot of them weren't able to launch Twitter successfully. That was a much more complex issue, it did not have a one-size-fits-all fix, so the team here worked as quickly as possible to address it but it caused a large number of users to not be able to use the product, even those who were trying repeatedly to figure out ways to get in. - uk.businessinsider.com
