Hi there! I understand you're having trouble with the OANN app not opening on your iPhone running iOS 18.7. Let's work through this together to get it fixed.

First, to help narrow things down—when you say the app "will not open," does it mean the app crashes immediately after tapping it, or does it just stay stuck on a loading screen? Also, have you tried any steps so far to fix it?

Meanwhile, here’s a step-by-step approach we can try:

1. Force Close and Reopen the App:
- Swipe up from the bottom of your screen and pause (or double-click the Home button if your iPhone has one).
- Find the OANN app preview and swipe it up to close it.
- After a few seconds, try opening the app again.

2. Restart Your iPhone:
- Hold down the side button and either volume button until the slider appears.
- Slide to power off, then turn it back on after about 30 seconds.
- Try launching the app again.

3. Check for App Updates:
- Open the App Store.
- Tap your profile icon at the top right.
- Scroll down to see if OANN has an update available; if yes, tap “Update.”

4. Reinstall the App:
- Press and hold the OANN app icon on your Home screen.
- Tap “Remove App,” then “Delete App” to uninstall.
- Restart your phone.
- Go back to the App Store and reinstall OANN.

5. Check Network Connection:
- Make sure your Wi-Fi or cellular data is working well.
- If possible, try switching from Wi-Fi to cellular or vice versa.

6. Check for iOS Updates:
- Go to Settings > General > Software Update.
- If an update is available, consider updating your iPhone, as sometimes app compatibility depends on the latest OS fixes.

If the app still won’t open after these steps, there could be an issue on their end or with your account. In that case, I can guide you on how to report the problem directly to OANN support.

Let me know what happens after trying these, and if there’s any particular step you’ve already done! That way, I can provide more specific help or advanced troubleshooting.

Are you ready to try these?
