About BankID: There was a regression in the app back in june that broke the app entirely. Back then I emailed the developers complaining about it, and their response indicated that there was no deliberate attempt at breaking BankID on GrapheneOS, and the specific developer who replied to me said he was a fan of the OS.

Biometric login was also confirmed to work around the same time. I can however confirm that it doesn't work on the latest app version. It complains that the webview isn't Google Chrome.

This is probably just an oversight. I will email them again; good chance they'll push a fix to recognise Vanadium webview.
