FCM Topics - Notifications not received on iPhone 4 (iOS 7)

Question

I am using Firebase to register for Topics and sending push notifications on iOS devices. Everything is working fine except for iPhone 4 (iOS 7), where I'm not receiving any notifications.

I'm able to send single device notifications to all including iPhone 4 (iOS 7), the issue is just with topic push notifications. My code below.

-(void)application:(UIApplication )application didRegisterUserNotificationSettings:(UIUserNotificationSettings )notificationSettings
{
    [[FIRMessaging messaging] subscribeToTopic:@"/topics/mytopic"];
    [application registerForRemoteNotifications];
}


       -(BOOL)application:(UIApplication )application didFinishLaunchingWithOptions:(NSDictionary )launchOptions 
        {
             if ([application respondsToSelector:@selector(isRegisteredForRemoteNotifications)])
                {
                    // iOS 8 Notifications

                    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(tokenRefreshCallback:) name:kFIRInstanceIDTokenRefreshNotification object:nil];
                    [application registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
                    [application registerForRemoteNotifications];
                }
                else
                {
                    // iOS < 8 Notifications

                    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(tokenRefreshCallback:) name:kFIRInstanceIDTokenRefreshNotification object:nil];
                    [[FIRMessaging messaging] subscribeToTopic:@"/topics/mytopic"];
                    [application registerForRemoteNotificationTypes:
                    (UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound)];
                }
        }

      // Register for remote notifications
      if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_7_1) {
        // iOS 7.1 or earlier
        UIRemoteNotificationType allNotificationTypes =
        (UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge);
        [application registerForRemoteNotificationTypes:allNotificationTypes];
      } else {

        UIUserNotificationType allNotificationTypes =
        (UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge);
        UIUserNotificationSettings *settings =
        [UIUserNotificationSettings settingsForTypes:allNotificationTypes categories:nil];
        [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
        [[UIApplication sharedApplication] registerForRemoteNotifications];
        // [END register_for_notifications]
      }

 // [START configure_firebase]
  [FIRApp configure];
  // [END configure_firebase]

  // Add observer for InstanceID token refresh callback.
  [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(tokenRefreshNotification:)
                                               name:kFIRInstanceIDTokenRefreshNotification object:nil];
