TestFlight doesn't accept build for external testing: "This build is not allowed for external testing."

Internal testing works fine, but when I submit a build for external testing, I get the following error message:


"This build is not allowed for external testing."


Does anyone know what that means?

Me too! I'm wondering if it is because I am building using the latest Xcode beta so I can build for iOS 11. But I noticed another problem - sometimes I get that message and sometimes the submit button just hangs and then the Feedbackt email address disappears from the Test Information page. Very strange.

Update: I tried rebuilding from XCode 8.3.2 which I was using prior to building for iOS 11 and ran into the same issue more or less. Must be standard ITC bugginess.
