Plist configuration options are not recognised

I am trying to get Geofencing working in my managed app but I am running into a hurdle when enabling ‘Background Location’.

Despite updating my app.json file with the workaround suggested in the documentation I keep receiving the following error when calling Location.startGeofencingAsync(taskName, region):

Error: Background Location has not been configured. To enable it, add `location` to `UIBackgroundModes` in Info.plist file.

As a managed app, I do not have access to the Info.plist file and updating the app.json file appears to have no effect.
I have tried both a macintosh machine and a windows machine as well as previous versions of the expo-cli from 18.0.0 --> 19.5.0
I would really appreciate some guidance or help to remove this error.
FYI, I can re-create the error by running expo init, expo install expo-location and adding the following to the app.js file:

timport React from "react";
import { StyleSheet, Text, View } from "react-native";

import * as Location from "expo-location";

export default function App() {
  Location.startGeofencingAsync("test", [
    { latitude: 37, longitude: 144, radius: 15 }

  return (
    <View style={styles.container}>
      <Text>Open up App.js to start working on your app</Text>

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: "#fff",
    alignItems: "center",
    justifyContent: "center"

And this to the app.json file:

  "expo": {
    "name": "alhmp",
    "slug": "alhmp",
    "privacy": "public",
    "sdkVersion": "33.0.0",
    "platforms": ["ios", "android", "web"],
    "version": "1.0.0",
    "orientation": "portrait",
    "icon": "./assets/icon.png",
    "splash": {
      "image": "./assets/alhmp.png",
      "resizeMode": "contain",
      "backgroundColor": "#151515"
    "updates": {
      "fallbackToCacheTimeout": 0
    "assetBundlePatterns": ["**/*"],
    "ios": {
      "supportsTablet": true,
      "infoPlist": {
        "UIBackgroundModes": ["location", "fetch"]

Hi @ahvmckay!

Unfortunately, the iOS Expo client app no longer has access to background Location :frowning:

But, you can use a custom Expo Client to acheive this! For more info read here->
