AirWatch Console 8.4
When a Notifications profile is applied to a supervised iOS device, any app specified in the profile that has not yet been installed and launched on a device will fail to launch the Allow Notifications pop-up. For example, if a Notifications profile has the AirWatch Agent configured, but the app is installed on a device after the profile is applied, then the user will never receive the Allow Notifications pop-up for the AirWatch Agent. Apps that are already installed on the device will receive the pop-up as expected.
