Mandatory ID verification fails, account will be suspended February 7th

I am registered and verified on Binance, but two days ago (Jan 25) I received a warning email from Binance demanding to re-verify my identity a second time for legal compliance, otherwise my account will be suspended on February 7.

This is my profile page, showing that I'm fully verified already, along with the account suspension notice.

To proceed with the verification, I'm required to use Binance's app to scan a QR code shown on the website. But this fails all the time: I can point the app to the QR code and scan it, but as it detects the code, the app turns into a blank screen and doesn't move forward.
