Hello! I understand that TV Listings Plus is showing a "no internet" message even though you do have internet, and you are able to view your scheduled programs. Let's figure this out together.

To start, could you tell me if you are using the TV Listings Plus app directly on your iPhone with iOS 15.1, or are you trying to view the service on another device? Also, does the "no internet" message appear at the moment you try to access live content, or does it come up even when opening the app?

In the meantime, here are some quick checks and steps you can try on your iPhone to help resolve this:

1. Check Network Connection Settings
Open your iPhone Settings, tap on Wi-Fi, and ensure you are connected to your Wi-Fi network. Try toggling Wi-Fi off and on again.

2. Restart the App
Close the TV Listings Plus app completely (swipe it away from the app switcher) and reopen it.

3. Restart Your iPhone
Sometimes a simple restart clears temporary glitches.

4. Reset Network Settings (If problem persists)
Go to Settings > General > Reset > Reset Network Settings. This will remove saved Wi-Fi passwords, so please be ready to re-enter them.

5. Check for Updates
Make sure both your iOS and the TV Listings Plus app are updated to the latest versions available.

6. Try Using Cellular Data
Temporarily turn off Wi-Fi and try accessing the app over cellular data to see if the issue is Wi-Fi related.

If the app still shows "no internet" but allows viewing schedules, it might be a connectivity handshake issue between the app and the server, or a caching glitch.

Please try these out and tell me what you observe. If needed, we can delve deeper into network troubleshooting or check for known service issues.

Are you currently connected via Wi-Fi or cellular on your iPhone?
