Hi! I’m Charlotte. I’m here to help with the Jigsaw World puzzle not loading on your WebKit device with Windows 10. To assist you best, could you tell me a bit more? For example:

- Does the app start but the puzzle never appears?
- Does it freeze or show an error message?
- Are you connected to the internet steadily?
- Have you noticed this happening suddenly or has it been ongoing?

While I wait for your details, I can suggest some general steps we can try to get your puzzle loading:

1. Refresh the browser or restart the app to clear memory hiccups.
2. Clear your browser cache and cookies as stored data might be causing issues.
3. Make sure your internet connection is stable and fast, as Jigsaw World requires connectivity to load puzzles.
4. Try loading the puzzle in a different browser like Chrome or Firefox to see if it’s a browser compatibility issue.
5. Restart your computer to reset any temporary glitches.

If these don’t fix the problem, I can guide you through more advanced steps or investigate if there are known server issues or updates for Jigsaw World.

Does any of this sound like what you’re experiencing? Would you like to try these steps together now?
