Hi @mbeames and @verres! Welcome to Pandora community.
I've removed the Yamaha device association with both of your Pandora accounts. When this takes affect, you'll automatically be logged out. However, this may not happen immediately, please be patient.
The following network troubleshooting steps, may also be helpful.
Shut down your Yamaha completely;
Unplug your modem and router, wait 10 minutes, and then plug them back in;
Wait five more minutes to allow the modem and router to fully boot back up;
Turn your Yamaha back on and try Pandora again.
Let me know if you continue to have trouble.
