Hi, My app works correctly in debug with Mac Catalyst and receive push, when I uploaded in TestFlight and installing from TestFlight not receiving any more push but the server of apple respond 200 ok. we don't use certificate but keyID.

Hello, we're currently working on an app for emergency organisations. In case of an emergency it's crucial to alert all users just in time. We've tested remote notifications. They're not really reliable for a time critical use case. Our idea is to use VoIP push notifications to alert the users. Before we start testing it, I would like to know if we'll run into an issue with the App Store approval if we just use VoIP PN without having VoIP functionality in our app. Regards, Enno
