Amazon dash button (part 2)

Hello folks,
can it be that the DashButtons no longer work because amazon has been deactivated in Germany?
Or how can I reactivate it? I can no longer prepare them in the app.

Can anyone tell me something more specific?

according to this post the buttons should be blocked on the router so that they do not get access to the internet to block them from ‘phoning’ to their homebase.
