Can you delete the Pandora app once more, I know you mentioned this before, but the last association I see on your account is from 2016.
Hold down the Pandora icon on your Home screen until all the icons start "shaking."
Then tap the tiny "x" that appears in the upper left of the Pandora icon, and confirm that you want to delete the app.
Then re-install Pandora via the App Store on your device.
Also, you mentioned you received the following message, "no compatible files found on this device", was this on your phone and does the message appear often? Can you take a screenshot of this message?
