Are you still having trouble with your Yamaha? Unfortunately, there isn't a way to sign out through the Yamaha MusicCast app. I can remove the connection from your Pandora account and have you try again.
No problem! I've gone ahead and removed the connection. Normally, I would say wait until you've been logged out before proceeding, but given that you're stuck in the log in, that won't work. For now, I recommend waiting at least an hour or two, and then power cycling your Yamaha by unplugging it for at least 5 minutes, and then restarting your phone.
I'd like to be sure that all the bases are covered, hopefully, this will help. Let me know how it goes.
