@LisaJ I moved your post over to this existing thread: Still hearing ads with Pandora Plus
It looks like you're subscribed to Pandora Plus, not Pandora Premium. However, you're triggering a complimentary session of Premium in order to listen to on-demand content, which is why you're seeing ads.
To listen to music without ads, make sure you are listening to one of your collected radio stations vs. trying to play a song or album on demand.
Check out the accepted solution to this thread for more information.
Hope this helps explain!
