Notifications with attachments do not work when the app is compiled from source code

[lucaardito]

Model Name: iPhone14
Software Version: iOS 18.1.1
App version: 2024.9.5-2024.986

Home Assistant Core Version
2024.11.3

Describe the bug
After compiling the app from the source code and setting my instance of Firebase, if I send a notification from HA, I only receive notifications with the title and text, and the attachment is lost. If I use the HA version downloaded from the app store, it works correctly.

Is there any option to be set to make it work? Or should a specific setting be placed in the Firebase console? The Android version works without any problem with the same setup.

To Reproduce
Compile the app from the source code, set up a custom Firebase project, change the URLs in the source code (Rate limit and push notification), and send a notification with attachments from HA.

Expected behavior
The notification with the image should be received.

After digging a bit I noticed that, when the notification is received, the Extensions-NotificationService.NotificationService class is never called.

final class NotificationService: UNNotificationServiceExtension {
    override func didReceive(
        _ request: UNNotificationRequest,
        withContentHandler contentHandler: @escaping (UNNotificationContent) -> Void
    ) {
        //...

I imagine that the didReceive method should be called when the notification is received.
