I've got a notification service extension which is working as expected unless the user a) turns the passcode for the iPhone on and b) turns on Auto-lock and the iPhone is locked when a push arrives If auto-lock is turned on and the phone is locked but passcode is not turned on, then the notification is displayed as expected. The iPhone displays a notification with the top line being the name of the app and the second line saying "Notification", which is neither the content within the push payload, not what is being set as the content within the extension. There's no difference in behaviour of the extension when passcode is enabled. Adding logging to the extension I can confirm the content is being replaced and posted as expected: NSLog("Going to post notification title: \(notificationContent.title) subtitle: \(notificationContent.subtitle) body: \(notificationContent.body)") contentHandler(notificationContent) The notificationContent is as expected and is identical when passcode is on off. Why is the iPhone displaying the notification incorrectly if passcode is turned on and the phone locked?

I'm running an app with the com.apple.developer.usernotifications.filtering entitlement and the filtering works fine with iOS 15. However I tried running it on an older phone / OS (iPhone 8 / iOS 13.1.2) and it does not work. Is this entitlement not supported with iOS 13.1.2? If so, what is the earliest iOS version that supports it? The handset logged this: The OS displayed: default 07:55:58.800825-0800 NotificationServiceExtension   Mutated notification request will not visibly alert the user, will deliver original content If the app is run on iOS 15, it says : default 07:20:27.251600-0800  SpringBoard        Mutated notification request will not visibly alert the user, will supress original content

We have an app which gets sent APNSs by the server and use a Notification Service Extension to intercept them. In my observations I've never seen throttling applied on the device to these pushes (unlike app directed push where its easy to observe happening if you let the batter run low for example). The Apple documentation says it may perform server side throttling, but when, how often, under what circumstances? If the app has 30 million users and the server sends them 10m or 100 pushes per day will it get throttled? Does anybody have any have any documented or observed info on this.
