Hello, Ujjaval. I'm testing the email report issue you've mentioned, but I can confirm that ending user sessions when a user is logged in via the web works just fine. We have a 15.7 version installed in house for testing, and that does appear to work as expected. What is it you're trying to do, and what behavior is seen when you say that ending sessions "is not working"?
