Notification issue in iOS 15 3

Question

The below function is triggered when notification is received in foreground and background. But it is not triggered in iOS 15.3

   func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void)

Could anyone help me with this? Thanks in advance.
