Hello! I see you're trying to watch T20 cricket highlights on the BBC Sport app but are getting a message that it's unavailable in Northern Ireland due to a georestriction. Let’s look into this together.

Content like certain sports highlights can sometimes be restricted by location because of broadcast rights agreements. This means some videos may not be available in all parts of the UK, including Northern Ireland in this case.

Here’s what we can try step-by-step:

1. Confirm Your Location Settings: Sometimes, the app or browser uses your IP address to determine location. Make sure your device’s location settings are on and accurate, and try restarting the app or browser to refresh location detection.

2. Try Accessing via BBC Sport Website: Since you are on Linux with WebKit, try opening the T20 cricket highlights directly on the BBC Sport website’s cricket section (bbc.com/sport/cricket). Occasionally, the app and website have different availability.

3. Check for BBC iPlayer Availability: Some cricket highlights may also appear on the BBC iPlayer, which uses similar location detection rules. Check if the highlights you want are available there.

4. VPN Consideration: If your IP address is somehow detected outside the UK or in a restricted area, the content may block you. If you are using a VPN, try disabling it; if not, using a UK-based VPN might work, but this is subject to BBC’s terms and conditions.

5. Clear Cache and Cookies: Sometimes cached data might interfere with location detection. Try clearing your browser cache and cookies and try again.

If after these steps you still cannot access the highlights, the restriction is likely due to rights agreements that the BBC must comply with, and unfortunately, they cannot be bypassed officially.

Would you like me to guide you on how to clear cache or check location settings on your Linux WebKit browser? Or have you already tried any of these steps?
