Hi there! I'm Charlotte, and I’d be glad to help you get your Jigsaw Puzzles Epic app working again. Could you tell me a bit more about what happens when you try to use the app? For example, does it fail to open, crash, freeze, or something else?

While I wait to hear from you, here are a few simple steps you can try on your Windows device with WebKit to see if we can fix it quickly:

1. Restart your device: Sometimes, a fresh start can clear up app issues. Hold down your power button, shut down completely, then turn your computer back on.

2. Check for updates: Make sure both Windows and your browser are up to date, as this can affect app performance.

3. Clear your browser cache: Since you’re using WebKit, try clearing temporary data and cache, which can sometimes interfere with web-based apps.

4. Try launching the app again after these steps.

If you’ve tried any of these already, let me know which, and what exact problem you’re seeing when you open the app. That way, I can guide you through more detailed troubleshooting!
