A fallback page appears when a scene that has been published only for AR or VR is opened on an incompatible device. (For example, if an AR scene is opened on a desktop computer).
The default fallback page displays QR code that viewers may scan with a compatible device to view the scene.
The fallback page can be customized in the publishing settings panel. Add a link to the site where you would like to redirect viewers. Your may want to include more detailed viewing instructions on your custom fallback page depending on context.
Fallback pages appear on any device, browser or social media platform that is incompatible with a the viewing mode of a scene. For example, the Facebook mobile app is currently incompatible with AR viewing. AR-only scenes shared on Facebook will redirect mobile users to the fallback page where users can copy the link and open in in Chrome to view it in AR.
