ReceivedRemoteNotification and DidReceiveRemoteNotification never get called


We implemented remote push notifications in our app. What we would like to achieve is that when our app is in the background, a remote notification comes in, the user clicks on the notification, we perform some tasks based on the notification information. I noticed that when the app was in the background, when a notification came in, in Appdelegate, DidReceiveRemoteNotification and ReceivedRemoteNotification never get called. There's no way for me to get the notification from userInfo. Has anyone experienced this issue? Is this a bug? Any help is greatly appreciated!

    Have you implemented the IUNUserNotificationCenterDelegate for iOS 10+? If so, DidReceiveRemoteNotification and ReceivedRemoteNotification will never be triggered when user click the notification to open your app.
    After setting the UNUserNotificationCenter.Current.Delegate = this; in your AppDelegate you should register the event below to handle the click event:

    public void DidReceiveNotificationResponse(UNUserNotificationCenter center, UNNotificationResponse response, Action completionHandler)
        var userInfo = response.Notification.Request.Content.UserInfo;
