Testflight: Cannot upload build, cannot download SDK
According to TestFlight, this is because:
On 2/19/2014 we announced that only Teams who have previously uploaded a build with the TestFlight SDK will be able to continue to upload builds with the SDK.
And this means that:
- If your team has never uploaded a build with an SDK or you are a new TestFlight user then you will not be able to incorporate any version of the TestFlight SDK.
