Standalone component to reproduce

We are experiencing an issue where the User Location Puck (the blue circle) does not render if the application is launched while the device's Location Services (GPS) are disabled, and then enabled while the app is running.

The puck only appears correctly if Location Services are enabled before the application starts.

We use next libraries and versions:

{
  "@rnmapbox/maps": "10.2.7",
  "expo": "54.0.25",
  "react": "19.1.0",
  "react-native": "0.81.5"
}

We use next libraries and versions:

import React from 'react';
import { StyleSheet, View, Text } from 'react-native';
import { MapView, Camera, UserLocation, Logger } from '@rnmapbox/maps';

// Optional: Increase logging to see location updates in console
Logger.setLogCallback((log) => {
  const { message } = log;
  if (message.match('Requesting location results')) console.log(message);
});

const styles = StyleSheet.create({
  page: { flex: 1, justifyContent: 'center', alignItems: 'center' },
  container: { height: '100%', width: '100%' },
  map: { flex: 1 },
});

class BugReportExample extends React.Component {
  render() {
    return (
      <View style={styles.page}>
        <View style={styles.container}>
          <MapView style={styles.map}>
            <Camera
              defaultSettings={{
                centerCoordinate: [-74.00597, 40.71427],
                zoomLevel: 14,
              }}
              followUserLocation={true}
              followUserMode={'normal'}
            />
            
            {/* The UserLocation component handles the "blue puck".
              It should automatically listen to location updates.
            */}
            <UserLocation
              visible={true}
              showsUserHeadingIndicator={true}
              androidRenderMode={'gps'} // Explicitly trying GPS mode
              onUpdate={(location) => {
                console.log('Location updated:', location);
              }}
            />
          </MapView>
        </View>
      </View>
    );
  }
}

export default BugReportExample;

Observed behavior and steps to reproduce

Steps to Reproduce:

1. Disable Location Services (GPS) on the device (Android).
2. Launch the application with the reproduction component.
3. Observe that the map loads (UserLocation is expected to be missing or waiting).
4. Enable Location Services (GPS) via the device System Settings / Control Center.
5. Return to the application.
6. Observe that the UserLocation puck (blue circle) does not appear, even though permissions are granted and the service is now active.

Expected behavior

The UserLocation puck should appear automatically (or after a re-render) once Location Services become available and the app receives the location update.

Notes / preliminary analysis

We have created a patch that fixes this issue. It has been tested and works as expected. We believe it would be a valuable addition to the library. Please find the proposed fix below
