Hi there! I understand that your Wildscapes game runs smoothly when offline but freezes when you're connected to Wi-Fi on your Kindle running Android 5.1.1. Let's work together to get this sorted out.

First, could you tell me if your device and the game itself are updated to their latest versions? Sometimes outdated software can cause performance issues, especially when connected to the internet.

In the meantime, here are some steps you can try:

1. Restart Your Device: Sometimes a simple reboot can clear any temporary issues.

2. Update the Game: Go to the app store and check if there's an update available for Wildscapes. Running the latest version can fix bugs that might cause freezing.

3. Check Wi-Fi Connection:
- Make sure your Wi-Fi signal is stable and strong.
- Try disconnecting and reconnecting to the Wi-Fi network.
- Forget the Wi-Fi network on your device and reconnect by entering the password again.

4. Clear Game Cache:
- On your Kindle, go to Settings > Apps > Wildscapes.
- Tap on Storage.
- Clear Cache (not data, to avoid losing your progress).

5. Close Background Apps: Sometimes other apps running in the background can interfere with Wildscapes.

6. Reinstall the Game: If none of the above helps, try uninstalling and reinstalling the game.

If after these steps the game still freezes with Wi-Fi but works offline, it could relate to the network environment or how the game interacts with online services on your device.

Could you please also check if other online apps on your Kindle work fine with Wi-Fi? That can help isolate if the issue is limited to the game or more general.

Let me know what you've tried so far or if you want me to guide you through any of these steps.
