Hi there! I understand you're experiencing an issue where Candy Crush is frozen on an ad. Let's see if we can resolve that quickly.

First, can you tell me if you've tried any steps to fix this issue yet?

Meanwhile, here are a few basic steps you can attempt:

1. Close the App: Try force-quitting Candy Crush. To do this, swipe up from the bottom of the screen (if there’s no home button) to view your open applications, find Candy Crush, and swipe it up to close it.

2. Restart Your iPhone: A simple restart can sometimes resolve app freezing issues. Press and hold the side button, then slide to power off. Wait for a minute, then turn it back on.

3. Check for Updates: Make sure both your iOS and the Candy Crush app are updated to the latest version. To check for app updates, open the App Store and go to the Updates tab.

If these steps don't resolve the issue, we'll explore more advanced options. Please let me know how it goes!
