title: Repeat interval issue in userNotification
body: <p>I am working on the reminder app. For eg. if I set the timings of 05:25 scheduling it to repeat at every 2 hours, it is reminded at the interval of every 2 hours but it doesn’t remind at the current time i.e. 05:25. </p>
  
  <pre><code>UNMutableNotificationContent *localNotification = [UNMutableNotificationContent new];
  localNotification.title = [NSString localizedUserNotificationStringForKey:@"Reminder!" arguments:nil];
  localNotification.body = [NSString localizedUserNotificationStringForKey:_getReminderName arguments:nil];
  localNotification.sound = [UNNotificationSound defaultSound];
  
  UNTimeIntervalNotificationTrigger *trigger = [UNTimeIntervalNotificationTrigger triggerWithTimeInterval:60*60*2 repeats:YES];
  
  
  UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:_getReminderName content:localNotification trigger:trigger];
  
  request = [UNNotificationRequest requestWithIdentifier:_getReminderName content:localNotification trigger:trigger];
  /// 3. schedule localNotification
  UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
  [center addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) {
      if (!error) {
           NSLog(@"add NotificationRequest succeeded!");
      }
  }];
  </code></pre>
