BlackBerry released a new API update as of UEM 12.7.2 that allows SandBlast Mobile to retreive the iOS device app list.
You only need to upgrade your UEM to 12.7.2 or above to gain this capaibility.
No configuration changes are required on the SandBlast Mobile dashboard to enable this functionality.
As a result of this synchronization, the App Store version of the SandBlast Mobile Protect app can be used instead of the Enterprise signed iOS version.
