I was working with 2FA and link shares, it appears I fail to read QR Codes when in dark theme (or system theme, in my configuration)
You may enforce light theme when displaying a QR Code
have a nice week !

Hi @Esa-mimbias , I tested both the 2FA setup QR code and the share link QR code in dark mode,
but both are already rendered with a white background and black modules.
They scanned correctly with authentication apps and QR scanners on my end.
Could you please share:
A description (or a redacted screenshot) of how the QR looks in dark mode
Steps to reproduce
Happy to work on this once we can reproduce it 🙂

I made several tests today with other devices and other code readers, and they all were conclusive. Looks like it was a phone issue rather than Pangolin issue.
I'm really sorry to have bothered you with this.
I've met this issue (QR Code incorrectly rendered in dark theme) by the past with some software (even famous one), and jumped too fast to the wrong conclusion.
