A testflight now would be very nice. Or at least before the public launch
As stated in https://github.com/corona-warn-app/cwa-documentation/issues/92 and https://www.coronawarn.app/en/faq/ , testflight builds will only be available to the Corona-Warn-App project team and our partners (German Federal Government, Robert Koch-Institute, BSI, BfDI etc.).
