By tapping Install, Email+ for iOS is installed to the device.
When a featured app or an update to an installed app is published to device users, those users see a badge that appears on the corresponding tab in the app catalog. The number on the badge indicates the number of apps or updates available. The availability of an update is determined by comparing the version number for the installed app to that of the newly-published app.
After importing Email+ for iOS into the app distribution library, the app appears in [email protected] on the device. Tap the entry for Email+ and follow the prompts to install the app.
