Hi there! I understand your Jigsaw Puzzles app isn't loading on your Kindle. Let's dig into this and get it working for you.

To start, could you tell me:
- Is the app not opening at all, or does it open but puzzles don’t load?
- Are you connected to Wi-Fi or cellular data?
- Have you tried restarting your Kindle or the app yet?
- Is the app updated to the latest version?

In the meantime, here’s a step-by-step you can try to get things running:

1. Restart Your Kindle: Hold down the power button and turn it off, then turn it back on. This clears temporary glitches.
2. Check for App Updates: Go to the Amazon Appstore on your Kindle, search for the Jigsaw Puzzles app, and see if there is an update available. Updating can fix bugs.
3. Clear App Cache and Data:
- Go to Settings > Apps & Notifications > See all apps > find Jigsaw Puzzles.
- Tap Storage, then tap “Clear Cache” and “Clear Data.” Note: Clearing data may reset your app login or progress if not synced.
4. Ensure Device Software is Updated: Go to Settings > Device Options > System Updates and install any available updates.
5. Check Your Internet Connection: Try opening a website on your browser to confirm your internet is working well. A poor connection can prevent puzzles from loading properly.

If the problem persists after these steps, please let me know what happened during each, and we can explore more options like reinstalling the app or deeper troubleshooting based on your Kindle model and OS version (Android 9).

Are you okay to try these first?
