Feedback from Nitrokey (I'm working with them): 1) We are changing our warehouse process, adding a technical QA step, so that such mistakes won't happen anymore. Sorry for the trouble. 2) As you noticed, the former U2F is going to be replaced by a new FIDO U2F device which contains a full USB plug for better reliability, is more durable and has a touch button.
