Apple has now shut down Google’s ability to distribute its internal iOS apps, following a similar shutdown that was issued to Facebook earlier this week. A person familiar with the situation tells The Verge that early versions of Google Maps, Hangouts, Gmail, and other pre-release beta apps have stopped working today, alongside employee-only apps like a Gbus app for transportation and Google’s internal cafe app.

We’ve reached out to both Apple and Google to comment on the situation, but neither company responded by publish time.
