How can I uninvite user and block them from using my licenses?

License owners of multi-user licenses are able to block users through their Account Management Portal here: my.atlasti.com

If you block users, they will stay in the list and you would need to unblock them, for the user to gain access to your licenses. As soon as you unblock them, they will regain access.
