iPhone Duo: CarPlay safeAreaInsets remain zero while guidance cards obscure the map

We are experiencing a CarPlay layout issue on a physical iPhone Duo using CPMapTemplate and CPNavigationSession.

When guidance cards appear, safeAreaInsets remain zero on the supplied CPWindow, its root view, and our map view. The location marker therefore stays centered and is obscured by the guidance and ETA cards.

On a working non-Duo iPhone, the left inset updates correctly and our app shifts the map center accordingly. Apple Maps also shifts the location marker correctly on the affected Duo and displays smaller guidance cards.

Environment

  • iPhone Duo
  • iOS 27.1
  • Xcode 27.1

Is this a known issue? Is there a new public API or configuration requirement in iOS 27+ for obtaining the unobscured map area?

This is a known issue in iOS 27.1. Could you please verify whether you can still reproduce this on iOS 27.3 Beta 1? If you're able to, please file a Feedback report via Feedback Assistant and share the Feedback ID here for our records.
