Hello,
Thanks for the purchase!
Do not worry about that. We don’t have strict requirement to add license codes and replacing them from one domain to another. The license is for one live domain, and you can use plugins on development, staging or other types of temp domains that are meant for testing or development. Current system for checking the license compliance is not too strict and will only flag licenses if they detect concurrent usage on multiple top level domain, and even if that happen, I will first reach out to find out the reason (some users do use top level domains for testing purposes).
Best regards,
Milan Petrovic
