Hi there! I understand your Hay Day game isn’t loading on your Kindle with Android 11. Let me help you get it up and running.

First, just to clarify—when you try to open the game, does it get stuck on the loading screen, crash immediately, or show an error message? Any detail helps!

Meanwhile, let's try some steps that have worked well for this kind of issue on your device:

1. Clear the app cache:
- Go to your Kindle’s Settings.
- Tap on Apps & Notifications (or just Apps).
- Find Hay Day in the list and tap it.
- Tap Storage & Cache.
- Tap Clear Cache. This won’t delete your game progress, it just removes temporary files that could be causing trouble.

2. Force Stop the app:
- From the same place in Apps settings for Hay Day, tap Force Stop to completely close the app.

3. Restart your Kindle:
- Power off your device fully.
- Wait about a minute.
- Power it back on. This refreshes your device’s system and network connections.

4. Check your internet connection:
- Hay Day needs a stable internet connection to load.
- Try switching between Wi-Fi and mobile data to see if that helps.
- Make sure your connection is strong and not dropping out.

5. Ensure Hay Day is updated:
- Go to the Amazon Appstore or Google Play Store (if available on your Kindle).
- Check for any updates to Hay Day and install them.

6. If it’s still not loading after these, you might want to uninstall and reinstall the game (make sure your game progress is backed up via your Supercell ID or Facebook account to avoid losing progress!).

Would you like me to guide you step-by-step through any of these? Or, if you have tried some of these already, please let me know what you have done so I can avoid repeating and help you more deeply.

Looking forward to your reply!
