Before you can use this example, you need to complete a few steps. First, in your developer account go to the "Manage Channels" section and select "Use for billing testing" for one of the channels. Then, create a root user for testing in the "Manage Users" section, using the same email address as your developer account and Roku device. Additionally, ensure that you have created a product for the channel you have marked as billing testing, under the "In Channel Products" section. Once you have completed these steps, you will be able to see the main screen with the sign-in and sign-up buttons in the example.
