YubiKey NFC scan is never requested on iOS

[Heptite]

YubiKey is enabled and working for desktop login, but the iOS app doesn't request a scan of the YubiKey at all. I can just log in with my master password (and without any form of 2FA).

I feel like an idiot now. I had to revoke the 30 day trust for the device and then it wanted 2FA, offering YubiKey as one of the options.
