I have created a project using studio and also created a QR code trigger. After scanning the QR code, it brought me to the launch page. However, after clicking on the ‘launch’ button, my AR did not launch.
Please make sure you have published your experience to the project created on my.zap.works that contains this QR code. When scanned the QR code should launch into either WebAR / the Zappar app (depending on which it is set) and automatically launch the experience. If your experience is image tracked, you will also need to look at the target image for your content to appear.
