There could be several reasons why your Apple Podcasts app is not working. Here are a few troubleshooting steps you can try:

1. Check your internet connection: Make sure you have a stable internet connection. You can try switching between Wi-Fi and cellular data to see if there's a problem with your network.

2. Update your device: Make sure your device is running the latest version of iOS. Go to Settings > General > Software Update to check for updates.

3. Update the Podcasts app: If you're not using the latest version of the Podcasts app, update it from the App Store.

4. Restart your device: Sometimes a simple restart can fix many issues.

5. Check Apple's System Status: Apple provides a system status page where you can check if any of their services are experiencing issues. You can access it at https://www.apple.com/support/systemstatus/

6. Reinstall the Podcasts app: If none of the above solutions work, you can try deleting and reinstalling the Podcasts app. Please note that this should be your last resort as it might result in lost data.

If you've tried all these steps and are still having issues, you may need to contact Apple Support for further assistance.
