Bug: Unable to add an account to 1Password on iOS when using a Security Key for 2FA

Have 2FA with Yubikey 5ci
iOS app was having trouble editing passwords.

So I reinstalled the app
Unable to login again
Deauthorized the iOS app using a web login on Mac
Deleted the iOS app
Reinstalled the iOS app
Login fails with “ We weren't able to sign in to your
account. Maybe there's a typo? Check your sign-in details and try again.”

Verified the login and password and am able to login with a safari browser, which prompted me for a Yubikey.

But app doesn’t prompt for a Yubikey, just fails to login (note:credentials are verified to be correct)

iOS app is not usable. Please help
