Hi @Dawdenma,
Greetings from the Roku Community, and thanks for raising this concern directly with us!
We understand you want to view the Roku camera horizontally. We're happy to assist you. Please ensure that the auto rotation is off since it will prevent your phone from being viewed horizontally.
We hope this helps. If there's anything else that we can do to assist you, please let us know.
Best regards,
John
