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.

It an app receives a Voip push, but has to terminate the call, then if this happens a few times the OS is terminating the app (Message from debugger: Terminated due to signal 9) and then it stops delivering future pushes to the app.i.e. with code let endCallAction = CXEndCallAction(call: callUUID) let transation = CXTransaction(action: endCallAction) self.callController.request(transation) { (error) in } provider.reportNewIncomingCall(with: callUUID, update: callUpdate) { error in Model.priorityLog("GRUNT reportNewIncomingCall completion error \(String(describing: error))") completion() }

I wrote a notification content extension which with 10.1 was working perfectly and reliably - it was getting called 100% of the time, as it should, and eveything was great and working as it should.But now with 10.2 I just cannot get the bugger to work at all - the extension just isn't being called by the OS (actually it was called once out of about 30 attempts and on that one occasion the UNNotificationExtensionDefaultContentHidden YES flag was ignored, which it didn't use to be with 10.1)Anybody else having problem with content extensions with 10.2, but if not is there some trick or tweak or change you applied to get them to work?
