I wouldn't mind sending in a complaint to both BankID (allow biometric login) and of course DnB corpo edition.
Here is the github repo where banking app compatibilities are tracked: https://github.com/PrivSec-dev/banking-apps-compat-report
And it's rendered to a page here: https://privsec.dev/posts/android/banking-applications-compa...
Thanks anyway!
I don't know how to contact the engineering team. IIRC that is how the private app got fixed, someone got word to someone on the inside.
