Thanks for reaching out, I understand how disappointing this can be.
At this time, Pandora Premium features aren’t supported on Apple TV. Premium is available on our website and on select devices listed here. I’ve gone ahead and shared your feedback with our product team as they consider future improvements.
In the meantime, you can expand your Pandora Premium experience using Apple AirPlay from your iPhone to your Apple TV, or casting options from other supported devices.
