I am writing this about my recent purchase of WooCommerce Serial Number Pro. It is surprising that I cannot use this in my test environment and production. That is a basic need and not required to explicitly be told to you guys. Now you tell me how do I use a single key for test and production?
You can use the license in your test environment that is running locally. We do allow that. Apart from that, the single license is only valid for one live site. There should not be a problem if you test locally. You can also test plugin functions at our demo site. You should also take help from the documentations. Thank you.
