Currently, the WF app does not "Badge App Icon" (meaning display the little red circle in the upper right corner of the app icon and showing the number of unread messages).
We have enabled push notifications, and the badge app icon setting in iOS, removing and reinstalling the app, as well as opened a ticket with support. We are told this is as designed, which seems REALLY odd for a mobile app. If we have 21 unread WF Notifications, we'd like to see a badge with 21 in it so we know we need to hop into the app and deal with some things.
