MobileIron iOS App Multitasking is Disabled
Verify Location Services is enabled on the device for the MobileIron app by going to Settings | Location Services, then launch the MobileIron app once.
If you have email notifications for your users turned on they'll have received a similar email message in their local language.
Unfortunately if you've been an iOS for quite some time the title of the message will confuse you - you can't switch of Multitasking anymore. As is probably the case for lots of people (like me) you'll reach for Google and not read the rest of the message which explains the problem and lets you know how to fix it.
The issue is, basically, that the MobileIron applicaiton cannot access Location Services. This will either be because Location Services has been compeltely turned off on the device or that the MobileIron application has been specifically denied access to it.
The first step to resolving it is to open the "Settings" application;
|iOS7: Settings Application|
|iOS7: Settings > Privacy|
|iOS7: Settings > Privacy > Location Services|
