Sorry to hear that you're having trouble listening from your device.
If you haven't already, let's try running through the standard troubleshooting steps for your Android device. From your Android Settings, please try clearing the Pandora app data using the following steps (not to worry, we'll keep track of your profile and collection for you):*
Open your device Settings
Scroll down to find Pandora
On the storage details page tap Clear Data.
Keep in mind that the steps for each Android device is slightly different. If you have a Pixel, you can find helpful steps here.
Please note that you will be asked to log into your account after completing these steps. Let me know how it goes.
*Pandora Premium and Premium Family listeners may need to re-download some of their offline content after this. Pandora Plus users, however, should receive that offline content again automatically. If you have any trouble with your offline stations after this, please let us know.
