Hi there! I see you're having trouble with the Giant Eagle app not being able to load stores or find any stores near your location on your iPhone running iOS 18.7.1. Let's see if we can get this sorted out together.

First, just to get a better understanding, a few quick questions:
- Are you currently connected to Wi-Fi or using cellular data?
- Have you allowed the app to access your location in your iPhone’s settings?
- Is the app updated to the latest version in the App Store?

These details will help pinpoint the likely cause.

Meanwhile, here are some straightforward steps to try:

1. Check Location Permissions:
- Go to Settings > Privacy & Security > Location Services.
- Make sure Location Services is on.
- Scroll down to the Giant Eagle app and set location access to "While Using the App" or "Always."

2. Restart the App:
- Swipe up from the bottom of the screen (or double-press the Home button if your iPhone has one) to open the app switcher.
- Find the Giant Eagle app and swipe it up to close it completely.
- Reopen the app.

3. Refresh Network Connection:
- If on Wi-Fi, try toggling Wi-Fi off and back on.
- Alternatively, switch to cellular data or vice versa.

4. Restart your iPhone:
- Hold the side button and volume button, then slide to power off.
- Turn it back on after a minute and retry.

If after trying these it still cannot find stores, it might be an app issue or a server-side problem. You can also try signing out and back into the app or uninstalling and reinstalling the app to ensure the latest version is installed.

Should the problem persist even after these steps, I can escalate this for further investigation or check if there is an outage or other reported issues.

Please let me know what you find after giving those a try! Are you connected to Wi-Fi or mobile data right now? And did you check location permissions?
