React Native app reloads clicking on push notification

I am using react-native-notifications. I am getting push notifications perfectly but the issue is when the app is in the foreground and received push notifications. I clicked on the notification, the app reloads instead of resuming and the app is in the foreground all this time. It happens for every single push notification.
The event handler on click of push notification is being called and app reloads. I am just doing console in the handler.
Notifications.events().registerNotificationOpened()
Tried singleTop, singleTask, or singleInstance in manifest file. no luck

How can i display sendbird push notification when appllication is in foregroundmode?

I've implemented sendbird push notification in react-native. It's working fine when application is in background mode. but if application is in foreground mode then it's not display.
In code, I have also set sb.setForegroundState() and sb.setBackgroundState() method with application state.
So, anyone help me for solve out this ?
SendBird sends a push notification only when a user is disconnected. So, if the application is foreground and a user is connected, the app will not receive a push notification.
If you want to show a push notification when your application is in the foreground, you can show it using data in onMessageReceived() or onChannelChanged().
you can select "Send to devices both offline and online" from sendbird dashboard to receive notifications when the app is in the foreground
Sendbird -> Settings -> Notification -> Push notifications for multi-device users -> select "Send to devices both offline and online"

Withdraw/delete push notification in React Native

Our React Native app needs to send out push notification to a number of people (iOS and Android, app can be open, backgrounded, or closed), and when just one of these people performs a specific in-app action, we need our server to erase these push notifications from everyone's phones (again from either open, backgrounded, or closed). Is this possible to do for both iOS and Android?
You can send background notification (data notification if firebase) and implement frontend listeners to cancel all notifications received so far.

Facebook app clean notifications and badge.How?

I work on application, that uses Remote Notifications, and I am curious about something:
I notice, that Facebook app cleans notifications and application badge, when you read it in browser,even if you killed an app from app switcher.That happens when friend add something in your timeline.
So my question is: How this is done?
My understanding is when Application is killed from App switcher it goes into suspended state and cannot execute code.Is it possible to do this in my app?
As I understand they just are sending push notification with badge number set to 0.

How to enable-disable Notifications in settings app using sdk?

I want to use push notification in my app so first time it launches it will automatically ask for notification.So i want to enable-disable push notification settings for my app programmatically.Note-I do not want to unregistered my app just disable Alert,badge,Sound for my app in settings app.
You can't do this via the SDK. You'll have to inform the user that your app requires push notifications turned on, and then they'll have to go to Settings and turn it on themselves.
Apps have no control over the phone's settings, only its own.
