The Verge:
Apple has shut down Facebook’s ability to distribute internal iOS apps, from early releases of the Facebook app to basic tools like a lunch menu. A person familiar with the situation tells The Verge that early versions of Facebook, Instagram, Messenger, and other pre-release “dogfood” (beta) apps have stopped working, as have other employee apps, like one for transportation. Facebook is treating this as a critical problem internally, we’re told, as the affected apps simply don’t launch on employees’ phones anymore.
Facebook has no one to blame but itself. Time will tell how long they’ll be in Apple’s doghouse. This doesn’t affect the Facebook app many of us have on our iOS devices.
