Hi! I see you're having trouble downloading music on the Napster app on your WebKit-based Android 10 device. Let’s figure this out together. Could you tell me a bit more—are you seeing any error messages when you try to download? Also, is your device connected to Wi-Fi or mobile data when this happens?

In the meantime, here are some general steps we can try:

1. Check Your Subscription: Downloading music offline requires a Napster premium subscription. Do you have an active one?

2. Internet Connection: Make sure your device is connected to a stable internet connection while downloading.

3. Storage Space: Verify that your device has enough free storage available for downloads.

4. App Settings: Open your Napster app, go to Settings > Downloads, and check if there’s an option preventing downloads (like Offline Mode toggled off).

5. Clear Cache: Sometimes cached data can interfere; try clearing the cache for Napster in your Android settings (Settings > Apps > Napster > Storage > Clear cache).

6. Update App: Ensure your Napster app is up to date from the app store.

7. Re-login: Log out of your Napster account, then log back in to refresh the session.

If you’ve tried all this already, let me know which steps you completed, and if you have any specific error messages or behaviors. We can then dig deeper or look at some advanced options.
