Hi there! I understand you're having trouble connecting the Math Crossword app to your WiFi, which is preventing video ads from showing up for you to earn more points. Let’s work together to get this sorted out.

First, to better assist, could you share if this issue happens only with the Math Crossword app or with other apps on your Android 10 device as well? Also, are you able to browse the internet fine otherwise on WiFi?

Meanwhile, here are some initial steps you can try to fix the WiFi connection issue specifically for your app:

1. Restart your device: Sometimes a simple reboot clears temporary glitches affecting connectivity.

2. Check WiFi connection: Make sure your Android device is properly connected to WiFi and has internet access by opening a web page or another app requiring internet.

3. Clear cache and data for Math Crossword app:
- Go to Settings > Apps > Math Crossword.
- Tap on Storage.
- Clear cache first, then, if needed, clear data (note clearing data will reset app settings).

4. Check app permissions:
- Still in App settings for Math Crossword, tap Permissions.
- Ensure it has permission to access the internet.

5. Disable any VPN or proxy: These can sometimes block ads or app connectivity.

6. Update app: Check Google Play Store to ensure Math Crossword is updated to the latest version.

7. Reinstall the app: Uninstalling and reinstalling can fix corrupted files.

If you've already tried these, please let me know which steps you have done, so I can find more specific solutions for your Android 10 WebKit environment.

Are you satisfied with these steps so far or need help going through any?

I have rebooted umpteen times. It also happens with another Sudoku app. Otherwise internet works fine and it has a good signal strength. I try to disable the VPN next.

Thanks for the update! Since the issue affects both Math Crossword and another Sudoku app, but your internet connection is good overall, it suggests something is blocking these specific apps from connecting properly over WiFi.

Disabling the VPN is a smart next step, as VPNs sometimes restrict or reroute traffic in ways that prevent apps from accessing their servers, including ad services.

Beyond that, here are some additional things you can try, tailored for Android 10 and WebKit-based devices:

1. Forget and reconnect to WiFi:
- Go to Settings > Network & Internet > WiFi.
- Tap your WiFi network and select "Forget."
- Then reconnect by entering your password again.
This can refresh any network permission issues.

2. Check Data Saver or Battery Optimization:
- Sometimes Android restricts background data for apps to save battery or data.
- Go to Settings > Apps > Math Crossword and Sudoku apps > Data usage.
- Make sure "Background data" is allowed.
- Also check battery optimization and set these apps to not be optimized.

3. Clear DNS cache:
Sometimes your device caches DNS info incorrectly, disrupting specific domain access.
- Turn WiFi off and back on.
- Restart the router if you have access.
- Or consider switching to a public DNS like Google (8.8.8.8) in your WiFi settings.

4. Check for ad blockers or filtering apps:
- If you have any ad blockers, firewall apps, or security suites on your device, they might block ads or app data. Disable them temporarily to test.

5. Try Mobile Data:
- If possible, switch to mobile data briefly to see if ads and app connectivity work there. If yes, the issue is definitely WiFi or network specific.

If after these steps the problem persists, there may be a deeper network or app-specific issue. I can help you review logs or contact the app developers if you'd like.

Are you able to try these and let me know how it goes? Would you like detailed directions for any of these steps?

Sorted! I think. ( And I had installed reinstalled and cleared the data as well already) It seems the VPN was the issue. 🤞

Great to hear you might have it sorted out! VPNs can sometimes interfere with apps like Math Crossword by blocking certain connections or ad networks those apps rely on, which explains why disabling it helped. It's a common issue with VPNs affecting app connectivity and ad playback.

If you want, I found that Math Crossword has some community reports about connectivity glitches after updates but no big widespread VPN-specific issues documented officially. So it seems your fix aligns with typical VPN-related interference seen in apps relying on network access for ads and online features3.

For the best experience going forward, I recommend:
- Keeping the VPN off while playing or
- Configuring split tunneling if your VPN app supports it, so Math Crossword traffic bypasses the VPN.
- Making sure the app is up to date.

If you run into any other issues or want help setting up split tunneling, just let me know! Are you satisfied with this explanation and your current fix?
