@Boucher I'd recommend signing out of the app and signing back in, which will reset the download process.
Make sure to keep Pandora in the foreground of your device while the download completes.
If you continue to have trouble, check the download icon for the content you are attempting to download.
The two rotating arrows indicate that the content is still in the download process and the highlighted downward pointing arrow means the content has successfully downloaded.
Let me know if you continue to have trouble.
