Hi there,
Finally I got the solution for those who are unable to get the Notification message on screen.
It’s very easy.
First Slide the phone screen from left to right until you find the App Library.
Here You can see all the application on the screen.
Now, open the application that you want to restarts the Notification.
when you attempt to open the App it will ask you to allow the access.
Let it allowed and you will be able get the Notification on Screen again.
Done.
