didRegisterForRemoteNotificationsWithDeviceToken not called in ios8, but didRegister...Settings is

Question

I followed this thread, but the method didRegisterForRemoteNotificationsWithDeviceToken is still not called :

the documentation says :

After you call the registerForRemoteNotifications method of the UIApplication object, the app calls this method when device registration completes successfully

didRegisterUser appears well, but not did register notif.

Here is my code in the AppDelegate (the app version is 8.1) :

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    //register notif
    UIUserNotificationType userNotificationTypes = (UIUserNotificationTypeAlert |
                                                    UIUserNotificationTypeBadge |
                                                    UIUserNotificationTypeSound);
    UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:userNotificationTypes categories:nil];
    [application registerUserNotificationSettings:settings];


    return YES;
}

- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings
{
    //register to receive notifications
    [application registerForRemoteNotifications];
    NSLog(@"didRegisterUser");
}

-(void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error {
    NSLog(@"error here : %@", error);//not called
}

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
    /*
    // Store the deviceToken in the current installation and save it to Parse.
    PFInstallation *currentInstallation = [PFInstallation currentInstallation];
    [currentInstallation setDeviceTokenFromData:deviceToken];
    currentInstallation.channels = @[ @"global" ];
    [currentInstallation saveInBackground];
     */
    NSLog(@"did register notif");//not called
}

I also have background mode -> remote notification in the info.plist.

After a long dig I found that on 19 July, 2016 due to some error or updation at Apple's end , the didRegisterForRemoteNotificationsWithDeviceToken method would not be called even if every condition like Internet connection , Device and the methods used are perfect.

Refer to this link for confirmation https://forums.developer.apple.com/thread/52224

To verify please have a look in your other apps too. I had wasted my several hours but hope it helps someone. Thanks.
