This option is an additional feature for the professional and enterprise license. The PowerUser option allows for your licensed simultaneous sessions to establish unlimited sessions for each device at once.
Example: a professional license with 2 simultaneous sessions and PowerUser option allows for those 2 clients to establish unlimited sessions. The professional license is not bound to a specific device hence install AnyDesk on a preferred amount of devices and run AnyDesk on up to 2 of these concurrently as PowerUser.
The standard amount of simultaneous sessions are one. But you can add as many simultaneous sessions as you like.
