Hi! I see your Hardee’s app on your iPhone (iOS 15.8.5) only shows a white screen and doesn’t load further. Let’s work on getting that fixed for you.

To start, can you tell me:
- When did this issue begin? Was it after an app update or iOS update?
- Have you already tried closing the app completely and reopening it?
- Do you have a stable internet connection at the time you try to open the app?

Meanwhile, here’s a step-by-step guide you can try:

1. Force Close and Reopen the App
- On your iPhone, swipe up from the bottom (or double tap Home if you have it) to open the app switcher.
- Swipe the Hardee’s app preview up to close it fully.
- Then reopen the app and see if it loads properly.

2. Check Internet Connection
- Ensure you are connected to a strong Wi-Fi or cellular network. Sometimes the app can’t load content without a good connection.

3. Restart Your iPhone
- Hold the side button and volume up/down button (or just side button depending on your model) to power off.
- Turn the phone back on and try the app again.

4. Clear App Cache / Reinstall the App
- Unfortunately, iOS doesn’t let you clear cache directly like Android but you can delete and reinstall the app to clear corrupted data.
- To delete: Tap and hold the Hardee’s app icon > Remove App > Delete App.
- Go to the App Store, download and install the app again, then log in.

5. Check for iOS or App Updates
- Go to Settings > General > Software Update to see if there’s an iOS update available.
- Open App Store, tap your profile icon > scroll to see if Hardee’s has an update pending.

If after trying those steps you still encounter the white screen, it might be related to the app’s data fetching or a compatibility hiccup, especially since your iOS version is 15.8.5. Sometimes older iOS versions cause app glitches if the app supports only recent iOS versions.

Let me know what you’ve tried so far and if anything changed, so I can guide you further!

Are you satisfied with these initial steps?
