Not Receiving Incoming VoIP Push Notifications on iOS 18.4 (React Native App)

Hi Apple Dev Team,

We have a React Native application that includes call functionality using PushKit and VoIP notifications.

We are using APNS to send the VoIP notifications, and everything has been working smoothly on iOS versions up to 18.3.1.

However, after updating to iOS 18.4, we are no longer receiving incoming VoIP push notifications on the device. There have been no code changes related to our PushKit or notification logic — the exact same build continues to work correctly on devices running iOS 18.3.1 and earlier.

We're trying to understand if anything has changed in iOS 18.4 that affects VoIP push delivery or registration behavior.

Would appreciate any guidance, and happy to share code snippets or configuration if needed.

Thanks in advance!

I'm experiencing a similar issue. Push notifications work correctly on iOS simulators running 17.5 and 18.3.1, but they aren't showing up on the iOS 18.4 simulator. Interestingly, everything still works fine on a physical device running iOS 18.4.
