PLATFORM AND VERSION: iOS Development environment: Other: .net MAUI with vscode Run-time configuration: iOS 18.1.1 DESCRIPTION OF PROBLEM APNS notifications of apns-push-type pushtotalk sometimes stop arriving after switching networks. STEPS TO REPRODUCE We have created a simple app which can be used to deminstrate this issue. When you launch the app it displays the APNS token which you can then use fromn the Apple Push Console to manually send it PTT push notifications. https://github.com/trampster/PttPushNotificationIssue On an iPhone SE (we havn't been able to reproduce on our iPhone 11) Start the APP to register for the APNS push notifications Turn off the WiFi wait for 5 seconds Attempt a push to the app manually using the Push Notifications Console (this should fail, which is fine) Turn on Cellular and wait for it to connect Attempt to push to the app manually using the Push Notifications Console -> This fails, and all attempts to send an pushtotalk push notifications fail until the we switch network again. Send a push while offline before connecting to the new network seems to make it happen more often but hard to tell for sure. The results of the failed push in the console look like this: Delivery LogLast updated: 30/01/25, 16:45:06 GMT+13 Refresh 30 Jan 2025, 16:45:03.661 GMT+13 received by APNS Server 30 Jan 2025, 16:45:03.662 GMT+13 discarded as device was offline The device is actually very much online. Switching networks again oftern makes things come right. But it doesn't seem to come right by itself. We can't respond to network changes and do anything as the whole point of using push-to-talk push notifications is to wake up the app when in the background to answer a call, this means we are not running and therefore cannot respond to network changes to try to work arround this issue.

We are struggling with the lack of information provided by Apple re: Apple Push Notification service server certificate update We want help from other developers on HOW TO: make sure that both old and new server certificates are included in the Trust Store Exactly HOW is this done? What is the Trust store and how is it accessed? Is this done for our account once OR for each for the apps utilising APNs? Can anyone assist? Thanks Louise

@App Store Commerce Engineer hi, have you already implement something for handle server notification if user buy non consumable purchases product, how my server should know if user boutght something ?

Hi there, I’m currently working on an app designed for doctors to respond to life-threatening situations in hospitals. The goal is for critical alerts to trigger an alarm, regardless of whether the app is in the foreground or background. The critical alerts entitlement is already set up, but there’s a limitation: I can only attach a 30-second audio file to the notification, as I can’t run code to loop the sound when the app is swiped away. Does anyone have suggestions on how I might approach this problem? Thanks so much in advance!

Hello, I am encountering an issue with maintaining socket connections in iOS applications that need to remain active while in background mode. I am developing an application that requires maintaining an active socket connection in the background to receive real-time data. However, I've noticed that the socket connection is terminated as soon as the app enters background mode, which affects the intended functionality of my app. I understand that there are restrictions on background activities in iOS to preserve battery life and system resources. However, I would like to know what approach Apple recommends for handling this type of requirement. Are there specific APIs or configurations I should consider to ensure the socket remains active in the background? I would greatly appreciate any guidance or resources you could provide. I am eager to ensure that my app complies with Apple's guidelines and delivers the best possible experience for users.

The app will be wake up from killed status by silent notification or not? This is a question for years, from my test. It will wake up. Here the wake up means it will call the "didFinishLaunchingWithOptions" method. But we can not see the app in the "recent apps" list after switching home-screen up. So any Apple dev can give me a detailed explain for this?

Hello Everyone, We have some doubts regarding the apple notification alert update received in Oct 2024 for APNS server certificate update. Does this change is already live for sandbox environment? As we have checked on sandbox environment without changing any certificate its working and we are able to get push notification. Does that means our system does not need any change for production as well? If required where we should add https://www.sectigo.com/knowledge-base/detail/Sectigo-Intermediate-Certificates/kA01N000000rfBO. This certificate. For FYI we are using python library called django-push-notifications which internally call to the APNS server for push notifications.

Hello Everyone, I have some questions regarding the Apple notification alert update received in October 2024 for the APNs server certificate update. We are using Azure Notification Hub to receive push notifications. I confirmed with the Azure team, and they have already implemented the required changes. However, push notifications are still not working in the sandbox environment. Could you please provide any insights on this? Thanks.

We are attempting to update our app to use the PTT framework, as it has been made clear that this will be required in a future iOS version as opposed to using the Unrestricted VoIP entitlement we are using for several features of our app. However, the behavior of this framework poses some problems with implementing our app's functionality: It is not possible to programmatically join a channel when the app is not in the foreground. This hinders our ability to implement the Automatically activate radio stream feature of our app, which allows users who have opted into this feature to immediately begin hearing live PTT audio from their agency following an incident alert. Having the app constantly "joined to a channel" and using the restoration delegate could potentially work, however this is not ideal as this would result in the PTT UI needing to be displayed at all times, even when no radio stream is activated. We have a "Text to Speech" option that, when enabled, reads out the content of an incident alert after the alert sound has played. This currently happens by triggering an AVSpeechSynthesizer in the PushKit incoming push callback. It may be possible to render TTS audio on the fly in a Notification Service Extension and assign it as the notification's sound, if that is possible this is less of a problem. We also use the PushKit callback to, again if the user has enabled it, activate a "Shake to Respond" feature, allowing a short period of time after receiving an incident alert in which the user can shake their device to indicate that they are responding to the incident. There does not appear to be any way to have the level of background execution required to implement this using an NSE, and this is of course beyond the scope of the PTT framework. What options do we have to be able to continue to provide this functionality, without risk of it being disabled in a future iOS version?

I received the email from Apple: “Action Required: Apple Push Notification Service Server Certificate Update”. I'm not quite clear on what exactly I need to do. In my case, I have my own APN service on a DigitalOcean server and I have both .pem and .p12 certificate there. Can anyone help me?

Hi, Regarding the announcement about the Apple Push Notification Service (APNs) Server Certificate Update, I wanted to clarify whether it will impact my app’s push notification setup. I use Firebase Cloud Messaging (FCM) to send push notifications to iOS devices, and in my Firebase project settings, I have configured an APNs Authentication Key under the Apple app configuration tab (Firebase Console > Project Settings > Cloud Messaging > iOS app configuration). The authentication key I am using was generated from Apple Developer > Certificates, Identifiers & Profiles > Keys. Since I am using this authentication method instead of APNs certificates, are there any changes I need to be aware of due to the APNs server certificate update, and do I need to update anything in my current configuration to ensure push notifications continue to work? Thanks in advance!

Hello, I received this message below. I reached out to support but they said they can not help with something this specific. Any organization in the same boat? Which of the certificates in the provided link should I use? Hello, We’re reaching out with a final reminder that the Certification Authority (CA) for Apple Push Notification service (APNs) is changing. APNs updated the server certificates in sandbox on January 21, 2025. APNs production server certificates will be updated on February 24, 2025. To continue using APNs without interruption, you’ll need to update your application’s Trust Store to include the new server certificate: SHA-2 Root: USERTrust RSA Certification Authority certificate. To ensure a smooth transition and avoid push notification delivery failures, please make sure that both old and new server certificates are included in the Trust Store before the cut-off date for each of your application servers that connect to sandbox and production. At this time, you don’t need to update the APNs SSL provider certificates issued to you by Apple.

I am working with Notification Content Extensions and need to ensure that the content fits within the notification without scrolling. I want to know if there is any API that can provide the maximum available height for the notification content area. My goal is to avoid making the content scrollable inside the notification. Is there a way to dynamically retrieve the height of the notification space, so I can properly adjust the content layout and ensure it fits perfectly without requiring the user to scroll?

I've built an iOS & Watch OS app using Sign in with Apple & CloudKit exclusively. I'm now wanting to implement Push Notifications. I understand that I need a server to trigger the push notifications (I guess I could spool up a Node server somewhere or use Firebase), but I'd really like to not use any non-Apple backend services. Am I correct in understanding that I can do this with Push Notifications Console, or do I still need a separate backend?

Hi, I’m having issues with push notifications on my phone across multiple apps. When someone sends me a message, I only receive the notification 10 to 15 minutes later. For example, on WhatsApp, people say that my chat only shows one checkmark when they send me a message. I don’t know what else to do. I’ve already contacted Apple Support, visited an Apple-affiliated physical store, and followed all the recommended procedures. This is my first time using an iPhone—I bought it for professional use, but it’s practically useless if I don’t receive notifications instantly. They even told me that if I send it in for warranty service, there’s a 90% chance they won’t detect the issue, and the iPhone will come back with the same problem.

Hello. Recently, the users of our APP have reported using our products, and they can normally receive push in Hong Kong. However, when traveling to Japan or some countries and regions in Europe, push will not be received. we checked that -the cert is valid -the server get 'sent successfully' response -used pushtry to test the cert and token and it can receive push in app

How to create a Notifications Settings button in the Notification Settings similar to Facebook Notification Settings that will lead users to the app's internal settings page?

Hello, I have a couple of questions regarding the change of the Certification Authority (CA) for Apple Push Notification service (APNs) and I will be grateful for any answers. Does it require only making sure the server machine has the SHA-2 Root: USERTrust RSA Certification Authority certificate included in Trust Store (/etc/ssl/certs/USERTrust_RSA_Certification_Authority.pem with SHA256: 8a3dbcb92ab1c6277647fe2ab8536b5c982abbfdb1f1df5728e01b906aba953a) ? Should the Certificate Signing Request be updated (that one that is uploaded to https://identity.apple.com/pushcert/) ? Does it have any connection with the certificates that are created on https://identity.apple.com/pushcert/ ? Is the push type "mdm" affected too? Which certificate should be added and where specifically? Is it for Certificate Signing Request to https://identity.apple.com/pushcert/ or the certificate that is generated on https://developer.apple.com/account/resources/certificates/list or like mentioned in the first question? Can a certificate for sandbox environment be created on https://identity.apple.com/pushcert/ ? Thank you for any help.

Our team also received this email regarding the APNS. I don't know if I need to do something or not, since I haven't found any information in SAP Forums either. Our app uses the SAP Mobile Services push notifications. If any of you know any information about this, please let me know.

I have been working on adding a badge number count to my app, but have run into a really weird edge case. If I have a badge number on my app, delete the application and then re-install it, the badge number still persists on the app icon until I first open the app. I tried looking to see if there is a lifecycle method that is triggered upon uninstalling an app as well as if there is a specific userDefaults attribute to check in order to clear the badge, but I can't find any clear solutions. Does anyone know of a fix to this issue?
