in my developer account online, i created certificates and profiles and in Xcode, created an archive build, and submitted it successfully. in the 'my apps" portion of iTunes Connect, i see the build (it changed from "processing" to not). expecting to add beta testers, i looked for the Test Flight tab but it's not there. can anyone please explain to me what i should do or should have done differently? i've looked throughout the developer forums, and broadly throughout the internet and see no articles, posts or any relevant information.
