Hi @btumoine,
Thank you for reaching out to the community! I understand you’re concerned that Amazon Luna works on your Chromecast with Google TV but not on your Google TV Streamer (4K); it's a pleasure to assist you.
To help us gather more information, we’d appreciate it if you could submit your feedback through the Google Home app. This provides the details we need to look into this situation. For guidance on how to send it, please refer to this Help Center article: Submit feedback about your Chromecast, Chromecast with Google TV or Google TV Streamer device.
Regards,
Stephanie
