Welcome to the Roku Community, @habcat!
Rest assured that we will help you get back on streaming and suggest some steps. We also appreciate you reaching out for support.
In this case, it might be possible that your Roku remote is not successfully paired to your device. Can you please confirm if this is happening on your Roku Streaming Stick? Also, are you using the remote that came with it? If not, please let me know the specific model of your remote.
Here's our support article to help you identify your Roku remote.
In the meantime, you may visit this support article to help you pair your Roku remote: How to set up and pair your Roku voice remote
Keep us posted on how it goes!
