I work from home, and often use the Pandora app on my Vizio smart TV to play music while I work. My Internet connection is through Comcast. If I pause playback for more than a few minutes, it won't resume. The indicator on the TV screen will change from Pause to Play, but the music doesn't resume. I have to turn the TV off and back on again, then relaunch Pandora.

Hi @jfeldredge Thanks for posting.
What is the model and year of your Vizio TV? Are you on the latest firmware update? Are you connected via Wi-Fi or Ethernet cable?
