Unfortunately yes. I am hearing that it is related to managed [federated] Apple ID accounts. Even though it is my domain and I control these accounts, it is blocked on the apple side. Developers say it is not a restriction on their end. Unfortunately the only workaround is to logout of the managed Apple ID account, login to a consumer Apple ID account, download the software I need through TestFlight, then logout and log back in with the managed Apple ID which is quite a bit of work.
