Hi @Oliviawierzel
Sorry to hear you're having trouble with offline content.
I would recommend resetting all your offline content by manually signing out and back into the Pandora app.
I've often found it to be more effective to plug your phone into a power source, and leave Pandora in the foreground of your iPhone while your offline stations re-download.
You can view the download progress from Settings within the app.
Tap the Profile tab and then the Settings gear in the top right corner.
Next select Offline. You should now be able to view a progress bar indicating the current download status.
