Using a dev site first and license "Subscription attached to"

"Subscription attached to"
Can i add my dev site url here first then change it to my live site url after I have finished development?

Hello,

You can put your development website if you want ; you have the possibility to change the domain, that field is not "fixed".
We generally recommend to assign the production website to your license so you will have the cron-task, automatic updates, etc.
It's better to be notified on the production website for the updates than in your development website.

Regards,
