Hi there! I see you're having trouble with loading Dominoes Battle through Facebook on your iPhone running iOS 18.7. I’d love to help you get this sorted out. To start, could you tell me a bit more about what exactly happens when you try to load the game via Facebook? For instance:

- Does the game show a loading screen that never finishes?
- Are you seeing any error messages, like connection errors?
- Are you accessing it through the Facebook app or a browser on your iPhone?
- Have you tried any fixes on your own yet?

This will help me guide you better. Meanwhile, here are some general steps that usually help resolve Facebook game loading issues:

1. Check Your Internet Connection: Even if your internet seems fine, try switching between Wi-Fi and mobile data to see if one works better.

2. Force Close and Reopen Facebook: Double-click the home button (or swipe up if no home button) and swipe away the Facebook app to fully close it, then open it again and try loading the game.

3. Avoid Using “Recent Games” Shortcut: Instead of clicking the recent games link or icon, try searching for Dominoes Battle manually inside the Facebook app and start the game through that.

4. Restart Your Phone: A quick power off and on can clear temporary glitches.

5. Update Facebook App: Ensure you have the latest version of the Facebook app installed from the App Store.

6. Clear Facebook Cache (if possible): iOS apps don't have an explicit cache clearing option, but uninstalling and reinstalling the Facebook app can help clear corrupted data.

If after these steps the game still does not load in Facebook, please let me know. We can then try some more advanced steps or check for any server-side issues affecting Dominoes Battle.

Does this sound okay to start? And have you already tried any of these?
