I am facing the same issue while trying to migrate to 201409. Using
GetRefreshToken sample code i created the refresh Token.
I am trying to use the same refresh token that was generated and trying to
generate GoogleCredential with OfflineCredentials am i missing something or
something changed.
Thanks
Gopi
