Hello! I understand that videos and heats on the World Surf League app show just a black screen when you try to watch them in Microsoft Edge, and you also have Norton Antivirus running. Let's get this sorted out together.

First, to clarify: Are the videos failing to load only on the World Surf League app, or does this happen on other video sites like YouTube as well?

In the meantime, here are some steps that commonly help resolve black screen issues on Edge when Norton Antivirus is active:

1. Disable Hardware Acceleration in Microsoft Edge
Hardware acceleration lets your browser use your graphics card to load videos and animations more smoothly, but sometimes it causes display issues like black screens.
Here's how you can toggle it off/on:
- Open Edge and go to Settings (click the three dots top-right)
- Choose System and performance
- Find Use hardware acceleration when available and turn it off
- Restart Edge and try playing the videos again
If this doesn't help, try turning it back on and restarting again, as toggling it sometimes resets display rendering glitches.

2. Update Norton Antivirus and Run Autofix
Sometimes old antivirus definitions or features can interfere with web video playback.
- Open Norton and run LiveUpdate to make sure the app is up to date
- After updating, restart your PC
- If problems persist, run the Norton Autofix tool from the support menu—it helps repair common network and display-related issues

3. Check for Conflicts or Network Blocks by Norton
Norton may have some web protection or firewall rules that block certain streaming content.
- Open Norton, go to the firewall or web protection settings
- Temporarily disable web protection and check if videos play
- If video playback works only when disabled, whitelist World Surf League’s website in Norton’s exceptions

4. Clear Browser Cache and Cookies
Sometimes corrupted cache files can cause video playback issues:
- In Edge, go to Settings > Privacy, search, and services > Clear browsing data
- Select Cached images and files and Cookies and other site data
- Click Clear now and restart Edge

5. Test in InPrivate Browsing Mode
Open an InPrivate Edge window (Ctrl + Shift + N) and try playing the videos there. If it works, the issue may relate to extensions or stored data.

If you have already tried any of these steps, let me know which ones so I can guide you to more advanced troubleshooting.

Would you like me to walk you through the steps right now? And also, does the issue happen only on your Windows 10 machine with Edge, or elsewhere as well?
