Hi there! I’m Charlotte Green, here to help you with the Global Entry app not loading on your iPhone running iOS 18.7. Let's get a bit more info first: when you say the app won’t load, do you mean it crashes immediately after opening, just shows a blank screen, or something else? Also, did this issue start happening recently or after an update?

This will help me guide you better. Meanwhile, here are some general steps we can try to troubleshoot:

1. Force close the app and reopen it: Swipe up from the bottom (or double-click the home button if you have one) to bring up the app switcher. Swipe the Global Entry app off the screen to close it fully, then tap its icon to open again.

2. Check for app updates: Go to the App Store, tap on your profile icon at the top right, and see if there’s an update available for the Global Entry app. Installing the latest version can often resolve loading issues.

3. Restart your iPhone: Hold the side button and volume button until the slider appears. Slide to power off, wait 30 seconds, then turn it back on. This refreshes the device system.

4. Check your internet connection: Ensure you have a stable Wi-Fi or cellular connection. Try loading a website in Safari to confirm.

5. Reinstall the app: If none of the above work, tap and hold the Global Entry app icon, choose ‘Remove App’ > ‘Delete App’, then go back to the App Store and reinstall it. This can fix corrupted app data.

If the app still won’t load after these steps, it’s worth confirming if there are any program-wide issues. Recently, there has been a temporary suspension of Global Entry services by DHS due to funding matters, which might affect app functionality temporarily3 10.

Could you try those steps and let me know what happens? If it still won’t work, I can help you explore deeper steps or get in touch with support for you. Are you satisfied with this initial guidance so far?
