Issue: The option "Managed apps can transfer data to personal apps" is unchecked (Devices Menu), but attachments in the work profile Calendar can still be accessed by the device's personal applications
Cause: Okta Mobility Management can typically allow customers to enforce data separation between personal and business files. However, this IOS bug presents a gap in this fucntionality. It is a known issue which has been brought to Apple's attention. Note that this issue does NOT affect attachments in the work profile's email messages.
