"Share AR" works only if you check both "Share" and "Share AR". "Share" allows sharing a link to the project without augmented reality. "Share AR" will send a link that opens the camera in the browser. Then you will need to point the camera at the corresponding marker-image or at any QR code (if the image is not set as a marker).
