I activated two factor auth for my google account.
1. factor: Password
2. factor: FIDO2 SoloKey Stick

But I cannot use my FIDO2 Stick.
Here is a screenshot: https://www.dropbox.com/s/5zrrhu0r3aki7 ... 6.png?dl=0

Freely translated "There was a problem, please try again or another option".
No detail info.

Is there a way to use a FIDO2 Stick with KMail?
