Lately, this problem keeps occurring: After a song ends, it keeps "playing" without any sound. "Dead air" may stay on for a minute or more. In other words, Pandora doesn't load the next song. The Android Auto screen displays the song and it shows the time elapsing well after the song's actual length. About the same time this problem appeared, I also noticed that after I "thumb down" a song, a long time passes before Pandora loads the next song. I don't know if these problems are related. I use Pandora only in the car, so I don't know if the problem is present when using a non-Android device.
@GME I have created a ticket with our support team for you.
They will be contacting you privately via email to help look into this further, so please keep an eye out for their message.
Thanks for your patience in the meantime!
