Not able to set up without QR Code

The latest app v7.3.1 asks for QR code from Body Cardio scale that I have, The scale was manufactured in 2016. The silly thing is that the scale's start up screen is "Hello Set Up", not QR code which is required from the latest app.
I'm unable to set up the scale at all unless there's an older version of app for me to install to the phone. The other option is for Withings Product team to fix the oversight. 

There's a whole heaps of threads from Reddit about this problem. https://www.reddit.com/r/withings/comments/1ixr4g3/body_scale_frustrations_on_apple_ios_devices/?share_id=cBZXBaAV1dJGD1ePr9l3i&utm_content=1&utm_medium=ios_app&utm_name=ioscss&utm_source=share&utm_term=1
