Camera and screen-share permissions are the most common reason a student can’t start. Here’s how to fix each one.

​
Camera is blocked

If your camera is blocked, allow it and reload:
1

Open the site's permissions

Click the icon at the left of the address bar (a lock, tune, or camera icon).
2

Set Camera to Allow

Change the camera permission to Allow.
3

Reload and try again

Reload the page and work through setup again.
Make sure no other app (Zoom, Teams, etc.) is using the camera. Close those, then reload.

​
”Share your entire screen” keeps appearing

When prompted, choose your whole screen or monitor — not a window and not a browser tab. If you pick a window or tab, you’ll see:
“You must share your entire screen, not a window or browser tab…”
Pick the entire screen and continue.

​
Face detection won’t load or is stuck

The test loads a face-detection tool, which can be slow on weak Wi-Fi.
  • Check your internet connection.
  • Wait for “Face detection is ready.” before reloading — give it a moment on a slow connection.

​
Screen sharing stopped

If your screen sharing stops during the test, share your entire screen again to continue.

​
On a phone, tablet, or iPhone/iPad

If your test uses screen monitoring, iPhones and iPads won’t work — Apple blocks screen sharing in every iOS browser. And if your teacher set the test to desktop only, no phone or tablet can start it. Use a laptop or desktop with Chrome or Edge.
