Hey guys, i'm new to Push notification. I have script in NodeJS which send push notification to user when someone comment's on his profile. But push notification is sent based on the device token so for example when A user logs in with his iPhone and then he log out and logs with account B from same iPhone then there device token will be same. So if someone comments on A's profile then that notification is sent on B's device which is currently logged in on the same iPhone. How to handle this type of situation ?
