License management occurs on the “your licenses” page, accessible after logging in to the site
If you have licenses that do not have a domain specified, you will see a "license settings" button
On the "License Settings" page, you can set the domain and subdomain of any of your licenses that have not yet been generated. You can specify data an infinite number of times. However, after generating a license, changing the domain and subdomain is no longer possible.
If your license has a domain and subdomain specified, you can generate a license by clicking on the "get license" button. After generating a license, changing the domain and subdomain becomes impossible.
You can generate a license as many times as you like.
When you first generate a license, in addition to prohibiting changing the domain name, the license expiration date will be set.
