Can anyone please explain in complete details the difference between internal and external testers in iTunes Connect Testflight beta testing? The difference here is just too brief. Does internal testers need to add UDID's of upto 10 devices? Or did apple completely removed UDID requirement now?
Can someone please explain what needs to be done to distribute and test app of upto 1000 users? If I have the clients iTunes Connect credentials, how do I share the app from his own account?
I know that there are too many questions asked in this thread which is against stackoverflow's policy, but i only need do's and don'ts of internal and external testing of this awful itunes connect testflight beta testing.
