Issue: Intercom Flutter works on Android but not on iOS (no console errors)

[JesusHdez960717]

Description

I have successfully integrated Intercom Flutter in my application, and it works perfectly on Android. However, on iOS, the messenger does not open and only shows the following error screen:

The issue is particularly confusing because:

• No errors are shown in the Flutter console.
• No exceptions are thrown.
• All Intercom-related calls appear to execute correctly.

Despite this, the Intercom Messenger never opens on iOS.

Environment

• Package: intercom_flutter
• Version: 9.4.22
• Platform affected: iOS
• Platform working as expected: Android

---

Initialization

try {
  await Intercom.instance.initialize(
    Environment.env.intercomAppId,
    iosApiKey: Environment.env.intercomIOSApiKey,
    androidApiKey: Environment.env.intercomAndroidApiKey,
  );
} catch (exc, stackTrace) {
  // Report error
}

---

Push Token Setup

try {
  final firebaseMessaging = FirebaseMessaging.instance;
  final String? intercomToken = Platform.isIOS
      ? await firebaseMessaging.getAPNSToken()
      : await firebaseMessaging.getToken();

  if (intercomToken != null) {
    await Intercom.instance.sendTokenToIntercom(intercomToken);
  }
} catch (exc, stackTrace) {
  // Report error
}

---

User Login

try {
  await Intercom.instance.loginIdentifiedUser(
    userId: _userPhone,
  );
} catch (exc, stackTrace) {
  // Report error
}

---

Opening the Messenger

await Intercom.instance.displayMessenger();

---

Additional Notes

At this point, I am unsure what might be misconfigured or missing on the iOS side. Since no errors are logged and the same implementation works correctly on Android, it is difficult to determine where the problem originates.

Any guidance on what could be causing this behavior on iOS, or what additional configuration/logging I should check, would be greatly appreciated.

@JesusHdez960717 Do you have the identity verification set up?
If yes, then make sure to pass the correct JWT.
