yes, with any release of crypto/acme with ACMEv2 support
What did you do?
_, err := lestencryptStagingV2client.Authorize("example.com")
What did you expect to see?
{directotyURL} doesn't support pre-authorization flow

this obscure error is returned because AuthzURL is empty for letsencrypt staging v2, and AuthzURL is not tested before calling POST.
