Closing a browser window doesn’t kill your session - it remains alive for 120 (maybe 60?) seconds by default, which can be configured here, in the Session Timeout section:

So you won’t see the “end\_session” message sent from the Perspective Session for at least one minute, maybe two.

I’ll look into the device\_id being empty, but I just tested it myself and it worked as expected…
