Hi there! I see you're having trouble with the Sankaku Anime AI Girlfriend app showing the message "failed to generate message. Please try again." Could you tell me a bit more about when this happens? For example, does it occur every time you try to chat with your AI companion, or only sometimes? Also, have you tried any steps to fix it yet, like restarting the app or your device?

Meanwhile, here are some common quick fixes to try on your Android 10 device with WebKit browser:

1. Check Internet Connection: Make sure your device is connected to a stable internet network, since message generation usually requires online processing.

2. Restart the App: Completely close the Sankaku Anime AI Girlfriend app and reopen it.

3. Clear App Cache:
- Go to Settings > Apps > Sankaku Anime AI Girlfriend.
- Tap Storage, then Clear Cache.
Clearing cache often resolves temporary data issues that might block message generation.

4. Update the App: Make sure you're running the latest version from Google Play. Outdated versions can cause compatibility issues.

5. Reinstall the App: If nothing else works, uninstall and reinstall the app to reset it.

If you've already tried all these or the error persists, it might help to check if the app has the necessary permissions, especially internet access permissions.

Could you please confirm which steps you've tried? That way, I can guide you to more advanced solutions if needed.
