I have some questions concerning android firebase database in order for me to go in the right direction. What I am trying to do: I have one client side that sends notification to one of the Two server sides I have. However I can not manage to send the notification to only one of the two server sides, when I send a notification it sends it directly to both Server sides, and this is what I am trying to figure out.
I am using an authentification for users in both client and servers sides, however is it essential to have two server sides? Or can I just filter my notifications with the users?
I am just asking this in order to go in the right direction. Thank you.
