Hello! I understand that you're having trouble with the Water Splash app not showing video ads, which prevents you from earning bonus darts and extra moves. Let's get this sorted out together.

To help me assist you better, could you please tell me:
- Are you seeing a blank or black screen when you try to watch the ads?
- Is the issue happening every time or just sometimes?
- Have you tried restarting the app or your device yet?

Meanwhile, here are some common steps that often resolve this issue on Windows-based devices using WebKit browsers:

1. Check your internet connection: A slow or unstable connection can prevent ads from loading.

2. Clear your browser cache: Cached data can sometimes interfere with ad loading. Since you use a WebKit-based browser, you can access the browser settings and clear browsing data, including cache and cookies.

3. Disable any ad-blockers or privacy extensions: These can block ad videos from loading. Temporarily disable them and try again.

4. Reset the advertising ID (if applicable): Though more common on mobile, Windows also has privacy settings related to ads. You can go to Settings > Privacy > General and toggle off "Let apps use advertising ID to make ads more interesting to you." Then toggle it back on after a minute.

5. Restart the app and your device: A fresh start can clear temporary glitches.

If you've tried these already, or if the problem persists, please let me know so I can guide you through advanced troubleshooting steps. Also, if you have any other details or screenshots, feel free to share!

Are you satisfied with these initial suggestions?
