Apple’s latest software update has attracted praise with the addition of the Night Shift mode and other features, but others have been left disappointed.
Users of older iPads, particularly the iPad 2 have been reporting glitches after updating to iOS 9.3.
According to Tech Radar, after installing the new update some users are receiving authentication errors rendering their devices completely unusable.
Apple has yet to comment officially but are asking individuals to send on details of the problem and how they have tried to fix it via Twitter DM.
