Hi there! I see you've mentioned that the AppAdvice app hasn’t been working for a couple of weeks now. To help you better, could you tell me a little more about what's happening? For example, does the app fail to open, crash, show an error message, or something else? Also, have you tried any troubleshooting steps already? This will help me guide you through the best options.

Meanwhile, just to clarify, AppAdvice has officially discontinued its operations recently. This could possibly explain why you are facing issues with the app since ongoing support and updates might no longer be available. If you are seeing no response from the app or it simply doesn't work, this might be related to the discontinuation announcement they made1 3.

If you still want to try a few things on your iPhone with iOS 18.6:

1. Restart your iPhone: This can clear temporary glitches.
2. Check for app updates in the App Store: Although unlikely due to discontinuation, sometimes an update helps.
3. Delete and reinstall the app: If the app is still available, this can help clear corrupt data.
4. Verify your internet connection: Since the app needs online access, ensure you have Wi-Fi or mobile data working.

If you share the specific behavior or any error messages, I can assist with more tailored steps or alternative app recommendations. How does that sound?
