Seems the system with my phone, cheapish smartish one, is that it wants data or wifi to keep the QFd QR code on the screen via email, of the face of the phone.
I had tried to find the way to screen shot, nothing worked, no 3 little dots to save to home screen.
I had to email the check in BP to myself, on the phone, and then, only with data open, (lucky my data is 42 days use all you want), and not per mb to keep open.
But each time I experimented by turning data off, (I no longer have a pocket wifi device), so sad, no BP.
Also, that 3 little dots would not appear on the BP, ...
Anyway, lesson learnt.
Screenshot, also did not work, how many times I tapped the QR image, nothing happened.
Also, as I was on the road, QF asked the answers to that 3 questions, to log in, lucky I kept a piece of paper with answers, and then, the system had the gall to send me an email of "unusual log in activity, is it you" tap ok if it is, all good I guess, at least we know when/if scammers are trying their way to get in.
I also did try to get a paper BP at a serve yourself kiosk at BNE QFd after having done OLCI, but it couldn't find me when I typed my name onto the screen, asks for last name first, then first name, no luck.
Also, the QF BNEd security check now follows the international screening way, ie, face sideways, with hands out at waist level, very different to the ADL dom screening, where its just walk through.
Last time I passed BNE QFd, it was face ahead walkthrough.
Ok, thanks everyone, learn new things all the time.
