Amongst other exciting new Apple product announcements yesterday, the release date for iOS 12 was confirmed to be 17 September 2018.
Whilst the release of an iOS update can be an exciting time of year, sometimes things aren't quite perfect right away and such issues can prevent us from being able to use our devices as we'd expect.
Because of this, updates on all managed iOS devices (running 11.3 and newer) are deferred by 7 days. This allows additional time for such issues to be detected and addressed.
All being well, the update to iOS 12 should be available for installation on your managed iOS device on 24 September 2018.
