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 Guest list builder option to the on position
The check-in app is now in Guest list builder mode and will only successfully scan Qflow Guest list builder QR codes. A grey circular Guest 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.
