I am not able find the exact solution.
My scenario is like I have registered a user with one device and then user logged into other device with same username password.
When I am doing that push notification is sending data to only one device while other dont get any thing.
Other scenario is like I login with one user and then log out and next time I login with other user. and if I send push notification to user A form user B then my device i.e user B is getting notification . How can I clear the data.
I know there is a way . We are using backend server as PHP server for handling notifications. How can I handle multiple login problem.
