Hi! I see you're getting error code 2004 in The Palace Project app on your Android 15 device. I want to help you fix that. To start, could you tell me when exactly the error pops up? For example, is it during login, while trying to borrow or read a book, or somewhere else in the app?

This will help me guide you through the right steps. Meanwhile, here are some general steps that often resolve common app errors:

1. Restart the app: Fully close it and open it again.
2. Check your internet connection: Ensure you have a stable Wi-Fi or mobile data connection.
3. Sign out and back in: Sometimes, re-authenticating clears credential glitches.
4. Update the app: Make sure you're running the latest version from the Google Play Store.
5. Clear app cache: Go to Settings > Apps > The Palace Project > Storage > Clear Cache to remove temporary files.
6. Reboot your device: A simple restart sometimes fixes underlying issues.

Once I know more about when the error occurs, I can provide more specific steps. Does that sound good?
