Hello Julius,
Thank you for your message.
Yes, you're absolutely correct. Please note additionally, that you don't need to register your mobile Viewer on Android/iOS device as it's free for use - you only need to register your Viewers running on Windows machines as described in
this guide.
In addition, please note that the minimum purchase for the Endpoint license is
10 endpoints. For more information please also see our
