Is anyone else unable to login to their PC-account, over the past couple-of-days ?

I keep getting sent to a page which wants me to login via a social-media account (I don't have one) or a Qbiz account (which I also don't have).

I only wanted to check, that I finally received my 500 Qmiles/sector bonus, from my recent trip. Or not, so I can send them a claim !

But it would be a nuisance, had I wanted to make a booking in the current Thailand International Travel Fair, while it lasts.
