Hi there! I understand you're having trouble with the Network TV app where closed captions aren't showing up and you're also unable to upgrade to the no-ad plan. Let's get this sorted out together.

First, to clarify a bit:
- When you say the closed captions are not working, is that on live TV, video on demand (VOD), or both?
- Are the closed captions completely missing, or do they disappear after certain moments like ads?
- And regarding the no-ad upgrade, are you encountering an error message when trying to upgrade, or is the upgrade option just not appearing at all?

This info will help me guide you accurately. Meanwhile, I'll walk you through some general steps for the captions issue and the upgrade problem.

### Fixing Closed Captions on Windows using Network TV WebKit app:
1. Check Closed Caption Settings in the App:
- While you’re watching a show, look for a "CC" icon or the settings menu inside the player and ensure captions are turned ON.

2. Check Windows Accessibility Settings:
- Go to Settings > Ease of Access > Closed captions and make sure captions are enabled system-wide. Adjust font and style if needed.

3. Reload the Stream:
- Sometimes captions glitch after ads or certain breaks, so try stopping and restarting the stream.

4. Clear Browser Cache for WebKit:
- Clear your browser’s cache and cookies, then reload the Network TV app. Corrupted cache can sometimes cause caption display problems.

5. Check Network and App Updates:
- Ensure your Windows 10 is updated, and if you have a Network TV app extension or desktop app, update it.

6. Try a Different Browser if Possible:
- Even though you use WebKit, see if Chrome or Edge gives you captions, to isolate if it’s browser-related.

### Troubleshooting No Ad Upgrade Issue:
1. Confirm Account Status:
- Log into your account on the website and check if the no-ad upgrade option is visible under your subscription settings.

2. Payment Method Verification:
- Sometimes, an invalid or outdated payment method can prevent upgrades. Ensure your payment info is current.

3. Clear Any Subscription Conflicts:
- If you have an existing trial or promotional offer active, it might block upgrades temporarily.

4. Try Upgrading from Another Device or Browser:
- Attempt the upgrade on your phone or a different browser to see if the issue persists.

5. Contact Billing Support if Needed:
- If none of these steps work, the upgrade issue might require action on the backend.

If the closed captions tend to disappear after ads or show inconsistent behavior, this is a known issue on some streaming platforms where captions reset during ad breaks. Usually, restarting the stream or re-enabling captions as needed is a workaround. The development team is often working on a fix to keep captions persistent through ads1.

Let me know the details I asked earlier, and if you already tried any of these steps, so we can focus on the next best action. Are you ready to start with these?
