In Beta 5, I can't upload my betas to TestFlight via Xcode. It always says I have no iTunes account (even though it has no problem signing anything). So I have to export the app in Xcode and use AppLoader to upload it.
I do have multiple accounts in iTC for 3 companies.
Is this a bug in Xcode (assumed), or do I need to do something specific in my configuration to make this work?
