I registered Jme through the website. How can I watch Jme on Amazon FireTV?

Jme is only offered in U.S. and CANADA. When setting up Amzon Fire TV,choose "English" for language. Is you choose "Japanese", it will take you to Amazon Japan account and you will not be able to watch Jme.
After Fire TV setting is complete, please search for the Jme app on the FireTV app Store and download it.
Once you've launched the app, log in with your Jme ID (registered email address) and password.
