how to change test app to live app in unity ads

Hello I dont know if this is the right place to ask questions about Unity ads, but I have asked the same on the unity ads forum and didnt get the answer so I am posting my question here. I have followed the steps about integrating the unity ads and everything works fine. Now I just want to know how can I set my app which I added in the unity ads admin as test app to live after when I have published the app to the store. The game id in unity ads will be same right because I will not be able to change it after I have published my app. Also I will publishing the app to multiple appstores and I want to know if same game id will work everywhere.

Thanks
