React Native Expo Google Maps Shows Blank White Screen

I am working on a React-Native app using Expo, and I am trying to integrate Google Maps on the home screen. However, the map does not load and only shows a blank white screen. Here’s the relevant code and configuration:

    import React from 'react';
    import { StyleSheet } from 'react-native';
    import MapView, { Marker, PROVIDER_GOOGLE } from 'react-native-maps';
    
    export default function HomeScreen() {
      return (
        <MapView
          provider={PROVIDER_GOOGLE}
          style={StyleSheet.absoluteFill}
          initialRegion={{
            latitude: 41.0082,
            longitude: 28.9784,
            latitudeDelta: 0.0922,
            longitudeDelta: 0.0421,
          }}
        >
          <Marker coordinate={{ latitude: 41.0082, longitude: 28.9784 }} />
        </MapView>
      );
    }

app.json configuration

    "ios": {
      "googleServicesFile": "./GoogleService-Info.plist",
      "supportsTablet": true,
      "bundleIdentifier": "com.xxx.xxx.xxx",
      "config": {
        "googleMapsApiKey": "XXX"
      }
    },

Steps I have taken

• I added the googleMapsApiKey under the ios.config section in app.json.
• I ensured the PROVIDER_GOOGLE is used in the MapView.
• The app has permissions for location access.
• I verified the API Key is enabled for Google Maps SDK for iOS in the Google Cloud Console.

Despite these steps, the map screen remains blank.

What I have tried

• Confirmed that the googleMapsApiKey is valid and has no restrictions.
• Checked that the Google Maps SDK for iOS is enabled in the Google Cloud Console.
• Cleaned the Expo cache with expo start -c.
• Rebuilt the app and tested on a physical device as well as on the iOS simulator.

Questions

• Am I missing any configuration for Google Maps with Expo on iOS?
• Do I need to include any additional native dependencies or steps since I’m using Expo?
• Could there be an issue with how Expo handles the googleMapsApiKey or permissions?
