   RN version: 0.59.9
   react-native-fcm: 16.2.4

2. What device are you using? (e.g iOS9 emulator, Android 6 device)?
   iOS only. It happens intermittently with various iOS devices, including iPhone 8, 9, and latest ones.
   NOTE: iOS version: 11.x and several others, including the recent ones.

3. Is your app running in foreground, background or not running?
   In all the cases, problem happens.

4. What is the problem?
   Push notifications stop working eventually on iOS devices. It happens out of the blue. The user needs to reinstall the App and only then the Push notifications start working.

Appreciate any solution, help or hints.
