Apple has temporarily pulled the iOS 9.3 update for older iOS devices such as the iPhone 5s, the iPad Air, and the iPad Air 2.
A few days ago, Apple started rolling out the iOS 9.3 update for all compatible devices. In the days that followed, however, an alarming number of users reported that installing the update rendered their devices unusable. Essentially validating these reports, Apple has just announced that it will pause the iOS 9.3 update for these older devices.
