I logged out of all my Pandora accounts, and then went through the process of re-registering and linking my Pandora account to my Sony account. It did not fix the problem. It's as if the device goes into a buffering loop. Previously, when it worked, if I selected Thumbs Up or Down, the buffer wheel would appear in the top right corner of the screen and then clear once the command was received, and the song playing displayed it had been Thumbed Up. Now the buffer wheel just spins until the song is done, and goes away when the next song starts playing.
