This page lists all the subscribers of your iOS mobile app. You can also revoke users to suspend the current session of the app on their iPhone or iPad. After revoking, they will have to restart the app. This is normally done if you forcely want your users to restart their app in case you have done any changes to the splash screen or the welcome screen.
You can also delete a user as per your requirements.
Entering criteria into the filter fields will help you find specific subscriber. Leaving the filter fields blank will show all the subscribers on your social network.
