Hi there! I see you're getting a "network error" message every time you open the HiTV app on your iPhone, even though you're connected to Wi-Fi. Let's work through this together.

First, just to confirm:
1. Is your Wi-Fi connection working fine for other apps or browsers on your iPhone?
2. Have you tried turning Wi-Fi off and on again, or switching briefly to mobile data to see if the error persists?

Assuming your Wi-Fi is generally fine, here are some step-by-step steps you can take to troubleshoot the HiTV app network error on your iOS 18.7 device:

1. Restart the HiTV app:
- Swipe up from the bottom (or double-click home button if your model has one) to bring up the app switcher.
- Find the HiTV app card and swipe it up to close it completely.
- Relaunch the app.

2. Check for app updates:
- Open the App Store, tap your profile icon, scroll to see if HiTV has an update pending. Installing the latest version might fix network-related bugs.

3. Restart your iPhone:
- Hold the side button and either volume button, slide to power off.
- Wait a moment, then power it back on.

4. Reset network settings:
- Go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings.
- This resets Wi-Fi networks & passwords, cellular settings, and VPN/APN settings to default, which can fix hidden connectivity issues. Just be sure to reconnect to your Wi-Fi afterward.

5. Reinstall the HiTV app:
- Press and hold the HiTV app icon until it wiggles, tap the "x" to delete it.
- Go to the App Store and download it again. This clears corrupted files that might cause network errors.

6. Check for system updates:
- Sometimes new iOS patches fix connectivity problems with certain apps. Go to Settings > General > Software Update and install any available updates.

If after these steps the error continues, it could be related to temporary server issues on HiTV’s side or the app needing specific permissions:

- Make sure HiTV has permission to use cellular or Wi-Fi data in Settings > HiTV > Cellular Data (enable if off).
- You might also want to check if there are any outages reported by HiTV online or on their community forums.

Would you like me to walk you through any of these steps? Also, if you've already tried some of these, let me know which ones so we can try something else.

Are you satisfied with this plan so far?
