I just bought and received email. Want to use also on my iPads but i cannot find the account id. Not in the email and also not in the app
May I know if you have purchased your Freedome license from the Apple app store? If yes, you can check this link on how to use your app store license in your other iPad.
There is also more information about the app store license here.
Thank you! This helped!
Glad to be of help, pstraetemans! You're welcome.
