Hi! I’m Pierre. I understand your Yahoo News app on your iPhone with iOS 15.7 is only showing 2 or 3 stories and then crashing to a white screen when trying to read them. Let's try to fix this together.

First, can you tell me if you’ve already tried closing the app completely and reopening it? Also, have you restarted your iPhone recently? Sometimes those simple steps help clear minor glitches.

If you haven’t, here’s a step-by-step approach to try:

1. Force close the Yahoo News app:
- On your iPhone, swipe up from the bottom of the screen and hold in the middle to open the app switcher.
- Find the Yahoo News app and swipe it up to close.

2. Restart your iPhone:
- Press and hold the side button and either volume button until the slider appears.
- Slide to power off, wait 30 seconds, then turn it back on.

3. Check for app updates:
- Open the App Store, tap your profile icon, and scroll to see if Yahoo News has an update pending. If yes, update it.

4. Clear app cache/data if possible:
- On iOS, you can try deleting and reinstalling the app, which clears its cached data:
- Press and hold the Yahoo News app icon, tap "Remove App," then "Delete App."
- Go back to the App Store, search for Yahoo News, and reinstall it.

5. Check your internet connection:
- Ensure you have a stable Wi-Fi or cellular connection as limited stories could be caused by connection drops.

If after these steps the problem persists, you might want to check if your iOS version is fully updated beyond 15.7. Some apps perform better with the latest system updates.

Would you like to try these steps now? Or have you already attempted some of them so I can help with a different approach?
