Hi @SorenDP, the APNS server asynchronously notifies Adobe Campaign that a device token has been unregistered (when mobile application has been uninstalled by the user in our case but not when customer disable notifications in the app itself -> this is could be a way how our app is developed). The mobileAppOptOutMgt workflow runs every X hours to contact the APNS feedback services to update the AppSubscriptionRcp table. For all the deactivated tokens, the field Disabled is set to True, date of the action is updated and the subscription linked to that device token will be automatically excluded from future deliveries.

Milan
