Hi there! I understand you can log into the Hidden City app, everything appears to load, but you can't click on anything to play. Let's try to figure this out together.

First, could you tell me if this happens every time you log in or just occasionally? Also, have you tried restarting the app or your device? Sometimes a simple restart resolves temporary glitches.

Assuming you have restarted, here are some steps to try next on your Windows 10 device with WebKit browser:

1. Clear the app's cache or browser cache. Cached files may cause interface issues.
2. Check you have enough free storage space on your device for the app to run smoothly.
3. Ensure your browser is up to date, and try clearing your browser's cache and cookies.
4. Try logging in with a different browser if possible, to rule out browser-specific problems.
5. Disable any browser extensions that might interfere with clicks or the app interface.
6. Check your internet connection stability as lagging connections can affect responsiveness.
7. If you have antivirus or firewall software, temporarily disable it to see if that resolves the clicking issue.
8. Lastly, uninstall and reinstall the Hidden City app or browser version to ensure a fresh install.

If after these steps you still can't click anything, it might be a known bug with the app or a temporary server-side issue.

Would you like me to guide you step-by-step through clearing cache or reinstalling? Or do you want me to check for any current known issues from the developer?

I'm here to help!
