Only request the App Tracking Transparency iOS permission when the app is focused (as it's not allowed in background).
This means that this code (which was a workaround):

useEffect(() => {
  const listener = AppState.addEventListener('change', (status) => {
    if (Platform.OS === 'ios' && status === 'active') {
      request(PERMISSIONS.IOS.APP_TRACKING_TRANSPARENCY)
        .then((result) => console.log(result))
        .catch((error) => console.log(error));
    }
  });

  return listener.remove;
}, []);

Can safely be replaced by:

useEffect(() => {
  if (Platform.OS === 'ios') {
    request(PERMISSIONS.IOS.APP_TRACKING_TRANSPARENCY)
      .then((result) => console.log(result))
      .catch((error) => console.log(error));
  }
}, []);
