@Bulldog2180 Nice to see you around the community.
It appears that you began a complimentary Premium session, which allows you to interact with an ad to access on-demand content at no cost.
These Premium sessions allow you to create playlists, and collect songs or albums.
However, you'll still have access to all of your stations under My Collection if you filter it by Stations.
When the Premium session expires you'll be returned to your regular Pandora app experience.
I can confirm your complimentary Premium session has already expired, and your account has now reverted back to the free service.
To learn more about Premium and these complimentary sessions please visit our Help Page.
I hope this is helpful!
