Just over a week following the release of iOS 9.3, Apple has followed up with iOS 9.3.1, which fixes a bug that led various iPhone and iPad apps to crash or freeze when web links were tapped.
AppleInsider reports that the issue originated from the Booking.com app. Apparently, this app and a few other, associated ones used an overly large app and associations file which resulted in crashes when links were tapped across a range of apps, including Safari, Messages and Mail.
As uninstalling the culprit apps did not solve the problem, a further iOS update was necessary. However, the issue was not influenced specifically by iOS 9.3. The same bug was reported on older iOS 9 versions – and, AppleInsider further claims, can be blamed instead on a recent Booking.com app update.
The release notes accompanying iOS 9.3.1, which you can read above, include no indication of any further changes to iOS 9 brought by this update. iOS 9.3.1 can be downloaded to compatible iPhone, iPad and iPod Touch models in the usual manner: by heading into Settings, General, then Software Update and, finally, Download and Install.
