I'm modifying push notifications sent from Apple's push notification service with a NotificationServiceExtension in my iOS project. I also set the APNS payload categoryIdentifier inside the extension. In the App's AppDelegate implementation file I registered the notification categories with the category that contains my actions. I handle the actions in the didReceiveNotificationResponse delegate method.
Everything works fine, except the actions below the extended push notifications are missing when the app is closed. When it's in the fore- or background, the action buttons are displayed.
Is there any way to make them work when the app is completely closed?
