Why does Apple even bother having these forums? Six pages of miserable developers pleading for help over the span of a year, and not a single word of assistance to be found from them. We are told our devices don't support TestFlight, but they will if it had been installed at some point in the past? That's simply insulting. With that other OS, I can install my app on any device I like in under a minute, and spend time making useful progress. But that doesn't help sell new hardware now, does it....
