On initial install, Safari reports an error: Cannot Open Page - Safari cannot open the page because the address is invalid.
On update, iRep minimizes the app, but does not update the software.
On iOS 10.0, 10.1, 10.2, and 11.0 and newer, this occurs if Installing Apps is restricted. This is done directly on the device or through Mobile Device Management (MDM) software. iOS versions prior to 10.0, and 10.3 permit installation even with the restriction enabled.
This prevents users from installing or upgrading apps from app store. However, users are able to install and update Veeva CRM.
