Apple has just released iOS 11 Beta 9 for compatible iPhone, iPad and iPod touch users. iOS 11 Beta 8 was released earlier this week.

Apple was releasing earlier iOS 11 betas on a bi-weekly basis. That timetable migrated to a weekly routine. Today, Apple is breaking tradition altogether with the release of iOS 11 Beta 9 completely out of the blue. This is odd given the fact that iOS 11 Beta 8 was released on Monday. Nonetheless, we have a brand new build at hand that likely fixes something crucial and everyone should go ahead and download it right away.
