Meetings on a MockFlow board use your browser's access to the camera and the screen. When that access is refused, MockFlow shows a short message above the meeting bar and the meeting carries on without your video or screen.

## Camera access was blocked

This message appears when you click the camera button (1) and the browser or your computer refuses the camera.

1. Click the icon at the left end of the address bar, next to **app.mockflow.com**, and set **Camera** to **Allow**. In Safari, open **Safari** > **Settings** > **Websites** > **Camera**.
2. On macOS, open **System Settings** > **Privacy & Security** > **Camera** and turn on your browser. On Windows, open **Settings** > **Privacy & security** > **Camera** and turn on camera access for your browser.
3. Click the camera button again.

If the message says **No camera available**, connect a camera, or close another app that is using it, and click the camera button again.

Turning the camera on is part of the Max plan. On Plus, meetings are audio only. See [MockFlow pricing](https://mockflow.com/pricing/).

## Screen sharing does not start

When you click **Share your screen**, the browser asks which window, tab or screen to share. Closing that picker without choosing cancels the share, and no message appears.

- If you see **Could not start the screen share**, check the system permission. On macOS, open **System Settings** > **Privacy & Security** > **Screen & System Audio Recording**, turn on your browser, then quit and reopen it.
- If the picker never appears, update your browser to the latest version. See [Supported browsers and other requirements](/docs/supported-browsers-and-other-requirements).

## Screen sharing and presenting do not run together

While someone presents the board, **Share your screen** is faded, and clicking it shows **Screen sharing is disabled while the presentation is active**. While someone shares a screen, clicking **Present** shows **Presentation mode is disabled while screen sharing is active**. Stop the share or the presentation first, then start the other one. See [Present a board live](/docs/present-a-board-live).

## Recording is not supported in this browser

From the screen share panel you can record a short clip and place it on the board. If you see **Recording is not supported in this browser**, use the latest version of Chrome, Edge or Firefox, or place a screenshot instead.
