Greetings from the Roku Community, @tbro8733!
We appreciate you reaching out for support and we'd be happy to further assist you in utilizing your Roku remote effectively.
In this case, it may be possible that your Roku remote is not paired successfully which is why the other buttons don't work. No worries! We have a support article dedicated to this matter:

Best regards,
Carly
