Hello! I see that your webcam works fine in the testing environment but not during the actual demo lesson for teachers on Native Camp. Let’s look into that together.

To better assist, can you tell me if you get any error messages during the demo lesson or if the problem is that the webcam just doesn’t show up or activates? Also, have you noticed if the demo lesson interface shows your webcam as "off" or unavailable?

Meanwhile, here are some steps that might help:

1. Close Other Apps Using the Webcam: Sometimes other programs (like Zoom or Skype) might lock the camera and prevent Native Camp from accessing it. Make sure to close any other apps that might be using your webcam.

2. Browser Permissions: Since you’re on a WebKit-based browser on Windows 10, check if the website has webcam permissions enabled. You can do this by clicking the lock icon near the URL and verifying camera access is allowed for nativecamp.net.

3. Refresh and Re-login: Sometimes simply refreshing the page and logging out then back in can reset permissions and connections.

4. Clear Cache and Cookies: Cached data can sometimes interfere with webcam functionality. Clear your browser’s cache and cookies, then try the demo lesson again.

5. Try Incognito/Private Mode: This disables most extensions and uses default browser settings, which can help identify if something is blocking the webcam.

6. Test Webcam in the Demo Page Specifically: If there is a preview or test camera button on the demo lesson page, try using it to see if the webcam is recognized there.

If those steps don’t resolve it, please let me know exactly what happens when you try to start the demo lesson (e.g., black screen, no video feed, error popup), and we can dig deeper from there. I’m here to get this working for you!

Are you comfortable trying those steps now?
