I had a problem with VoIP and Standard notifications with iOS 14.X only devices. My scenario is as follows: I have two iOS devices: User A, User B
- Interrupt the internet connection at user B
- User A call User B via my VoIP application
- Wait 15 seconds and activate the internet for B
Issue: VoIP notification of the call is not received for User B
Side effect: Randomly after this scenario, User B may no longer receive VoIP and standard (for text) notifications until I reboot the device.
PS: If user B is using iOS 12 or iOS 13 it works fine.
