I’m working in a little Yes/No experience in 8thWall, but many members of my team can’t react the application, they scan the QR code to be authorize and looks fine, but can’t start the experience. There is any guidance on this? ---

There’s not a limit on the amount of devices, but the preview QR code from the cloud editor is for single use. After scanning, it updates to a new QR code. For multiple users, scan one at a time, waiting for it to refresh between scans. ---
