I have an existing subscription to Prime video and Britbox. How do I add them to the roku express without getting charged for a second subscription? Thank you.
@Rigsbee Thanks for the note! Roku is a device platform that allows you to install channels (apps) to use/access services. You'll only need to install these channels from 'Streaming channels' on your device's Home screen, then use the option to sign in to each channel once you've installed them.
If you need more help logging in, feel free to reach out to Amazon Prime and/or BritBox support directly.
