Thanks for following up, @mkammes.
If you're having issues casting, try the following:
Check to see if there are any updates available for your Pandora app and update if needed.
Make sure your mobile device is connected to the same Wi-Fi network as your Chromecast device.
Try reinstalling or clearing app data for Pandora on your device.
Restart your Chromecast device by unplugging the power source and plugging it back in.
Restart the Pandora app on your device.
Run the Chromecast app to set up your Chromecast device again.
If you are still having trouble with Chromecast, please refer to Google's support page here. I hope this is helpful. Let me know how it goes.
