Hello, thank you very much for the explanation. I have always had a question about wanting to create an admin section in React and a React Native application for notifications. In React, the admin mode can add news, and when the news is published, it should reach the notification in the React Native application. Could you please teach us? :D

Hi, what will happen if we quit the app after sliding the app from system tray. I was trying your code but it didn't work when I quit the app and most of the e com apps work in that that, they send the notifications even if we quit the app. Is that supported in expo?

Do it will work in both devices like ios and android? with the same step?
