Your number of licenses = 1. This means that only ONE user with Employee or Administrator access rights can be in your box at a time. At the moment, such a user is logged into the system with the login
sony25@ukr.net. In order for you to be able to sit at the same time with him, you need to have at least 2 licenses. In order for you to be able to enter the box now, the employee on his device, from which he entered the box, must press the "Exit" button in the menu (the most bottom menu button)
