Well that was quick! Apple must have found a pretty serious bug in iOS 13.1 because the company already released a new update. iOS 13.1.1 was just released on Friday, a mere three days after iOS 13.1 was released. And let’s not forget that iOS 13.1 was released just four days after the initial iOS 13 release. What on Earth is going on over there!?
iOS 13.1.1 is almost certainly all about bug fixes as opposed to new features, but you should still install it immediately.
