subscribeToSignificantLocationUpdates doesn't work to me

[mitaxe]

Hi, I have such a code

RNLocation.subscribeToSignificantLocationUpdates(async location => {
  await AsyncStorage.setItem('location', JSON.stringify(location));
});

I want to track location change when the app is killed. I was using the simulator and used the location change feature to debug it.

Callback doesn't do anything in my case. Location permission is always,

Location updates are enabled.

Maybe it can be only simulated with a real device? But how to debug it, I don't want to use a train :)
