I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

Hi @jedai7, we're unable to reproduce the issue. May I know if you have added the notification service extension in your app?

Hi @rizafran sorry for long pause. I created
NotificationService.h with code
`//
// NotificationService.h
// NotificationExtention
//
// Created by n1090 on 11.10.2024.
//

#import <UserNotifications/UserNotifications.h>

@interface NotificationService : UNNotificationServiceExtension

I created NotificationService.m
`//
// NotificationService.m
// NotificationExtention
//
// Created by n1090 on 11.10.2024.
//

#import "NotificationService.h"
@import FirebaseMessaging;

@interface NotificationService ()
@Property(nonatomic) void (^contentHandler)(UNNotificationContent *contentToDeliver);
@Property(nonatomic) UNMutableNotificationContent *bestAttemptContent;
@EnD

@implementation NotificationService

• (void)didReceiveNotificationRequest:(UNNotificationRequest *)request withContentHandler:(void (^)(UNNotificationContent * _Nonnull))contentHandler {
  self.contentHandler = contentHandler;
  self.bestAttemptContent = [request.content mutableCopy];

  // Modify the notification content here as you wish
  self.bestAttemptContent.title = [NSString stringWithFormat:@"%@ [modified]",
  self.bestAttemptContent.title];

  // Call FIRMessaging extension helper API.
  [[FIRMessaging extensionHelper] populateNotificationContent:self.bestAttemptContent
  withContentHandler:contentHandler];
  }

• (void)serviceExtensionTimeWillExpire {
  // Called just before the extension will be terminated by the system.
  // Use this as an opportunity to deliver your "best attempt" at modified content, otherwise the original push payload will be used.
  self.contentHandler(self.bestAttemptContent);
  }

Sorry for the late revert, @jedai7. As discussed with the team, this seems to be a Unity-related issue since it's not reproducible in native iOS. With this, the original issue you filed in Unity SDK repo will be reopened to investigate. Thanks.
