The Pandora app may have been completely damaged and cannot be repaired until you reinstall it. The app's settings will be deleted when you uninstall it, therefore any settings errors will be gone as well. It will appear as if you are installing the program for the first time when you reinstall it.

1. On your iPhone 8, touch and hold any icon on the Home screen to delete the Pandora app. Tap the X in the upper-left corner of the Pandora app icon when the app icons start to jiggle.
2. When the pop-up message 'Delete Pandora?' appears, touch Delete to confirm.

Reboot your iPhone once you've successfully deleted/uninstalled the Pandora app, then follow these instructions to reinstall it:

2. Tap the Search button on the App Store's main screen (magnifying glass).
3. To find Pandora, go to the Search tab and type Pandora into the search area.
4. From the search results, locate and pick the Pandora app.
5. Tap Get and Install to download the app. To allow and confirm app download and installation, you may need to enter your Apple ID password.
