Licence Domain management between dev env and prod env

how to manange licence between dev domains and prod domains

Some of the themes allows you to install the theme on staging domains but the best case is to use the sub-folder ( domain. co / staging ) if you could.
When you move the the staging to live, there’d be no steps to re-register theme.
You should check the documentation first if there’s any information, if not, you could contact the item author.
