@cptcody I moved your post over to this existing thread as you're currently upgraded to Plus: Playlist to Station When Premium Session Ends
To clarify, playlists are only a feature of Premium. However, it looks like you've been initiating free sessions of Pandora Premium in order to access your customized playlist.
If you accept a complimentary Pandora Premium access session (by interacting with an advertisement in order to listen to content on-demand), you'll automatically be transitioned into the Premium experience, which looks a little different from our radio-only or Plus experiences. These Premium Access sessions allow you to create playlists, or collect songs or albums to listen to right away, rather than waiting to hear them play on a station. When your Premium session ends, you'll no longer be able to view your playlists.
This would explain why you are transitioned back to one of your stations before the full playlist plays.
You can also check out the accepted solution for this thread here.
Hope this helps!
