Hi there! I see you're having trouble updating Solitaire Grand Harvest on your Kindle device. Let's figure this out together. To start, could you tell me if you see any error messages when you try to update the game? Also, are you updating through the Amazon Appstore on your Kindle, or are you using another way?

Meanwhile, here are some common steps to address update issues on Kindle devices running Android 5.1.1:

1. Check Your Internet Connection: Make sure your Kindle is connected to a stable Wi-Fi network. Sometimes updates won't go through if the connection is weak.

2. Restart Your Kindle: Power off your device completely, wait about 30 seconds, then turn it back on. This can clear temporary glitches.

3. Clear App Store Cache: Go to Settings > Apps > find the Amazon Appstore, then tap on Clear Cache and Clear Data.

4. Try to Update Again: Open the Amazon Appstore, go to your apps and games, and see if Solitaire Grand Harvest is listed for update.

5. Uninstall and Reinstall the Game: If the update still won't start or complete, uninstall Solitaire Grand Harvest, then reinstall it from the Amazon Appstore. This often fixes corrupted files that block updates.

If you've already tried some of these steps, please let me know which ones, and we can dig into more specific solutions. Does this sound good to you?
