Once you have logged into the Qflow check-in app and downloaded your event:
Select the Settings tab (the far right tab option)
Scroll down and toggle the SCAN MODE List builder codes option to the on position
The check-in app is now in List builder mode and will only successfully scan Qflow List builder QR codes. A grey circular List builder icon will be added on the scan screen as a mode indicator.
PLEASE NOTE - If you attempt to scan any other barcode types while in Guest list builder mode the below on screen pop will appear.
