Hello,
Currently I can send push notifications to the registered users in my application, but if they have only downloaded the application and have not registered, is there a way to send those “not registered” a push notification?
No, as you don’t have any object in the database to send it to. How would the system know where to send the notification on a trigger? 
Thanks @alexid95, yes I know that but I didn’t want to accept it. haha:
