@A-toon Nice to see you around the Community.
It looks like your account is currently upgraded to Pandora Plus.
The ability to listen to a full playlist is only an option when upgrading to Pandora Premium.
It looks like you enabled a complimentary session of Pandora Premium, which allows you to interact with an ad in order to listen to content on-demand.
Because these sessions are funded by advertisements, your account reverted back to your regular service automatically at the end of the session.
This would explain why you weren't able to make it through the full playlist - your account reverted back to your regular service when the session was over.
Hope this helps explain!
