Apple sent out the message inviting developers to submit their apps for internal TestFlight testing back on August 5.
I've uploaded many builds in the last week, and none have made it out of the "Processing" status in the Pre-release tab of iTunes Connect. Some have been stuck in that status for almost a week now. I'm using the latest Xcode 7 betas and OS X version.
I contacted Developer Technical Support, who told me that they can't do anything to help with pre-release software.
On their advice, I contacted iTunes Connect Support, who after back and forth told me that "the issue is that I'm using a pre-release version of Xcode". Which is, of course, obvious and required to submit an iOS 9 build for testing.
So my question is: has anyone successfully submitted an iOS 9 beta build to distribute through internal TestFlight testing? Did Apple jump the gun in inviting us to test and were not actually ready, or am I just out of luck because of some reason, like using a feature which isn't actually complete yet?
If you did successfully submit and process a build, were you using iOS 9 features like On-Demand Resources?
