Apple released iOS 9.3 on March 21 and just 10 days later they were forced to release iOS 9.3.1 due to a significant web crashing issue when many users tapped on web links. After updating to iOS 9.3, users found that when they tapped a web link in Safari, Mail, Messages, Notes, Chrome and some other pre-installed or third-party apps, their iPhone or iPad would either freeze or crash.

The actual cause of the issue is yet to be discovered; however, there is speculation that the issue is related to “Universal Links and the Shared Web Credentials daemon.” This allows websites and apps to share login details.

To address this issue Apple released iOS 9.3.1 on March 31. Users can download the latest update over the air (OTA).
