• Point your camera at the floor or a piece of furniture first, then move it slowly up towards the wall. A bare white wall is hard for your phone to recognise.
• Move your phone gently from side to side. Holding it still or waving it around quickly does not help.
• Make sure there is enough light. In a dark room your phone has nothing to lock onto.
• The artwork appears at its true size, so you cannot scale it in AR. Want a different size? Close AR and pick the size on the product page.
• Still nothing? Open this page in Chrome or Safari. AR does not work in the browser of apps such as Instagram or Facebook.
