iOS build starts in portrait even though landscape is enabled (worked before)

Hey,

I’m currently testing my game via TestFlight on iOS and I’m running into an issue with screen orientation.

In my GDevelop project settings, I have the game set to landscape mode only. However, on all tested iOS devices, the game still starts in portrait mode when launching the app.

Only after manually rotating the device, the game switches to landscape.

Important:

  • This happens on multiple iOS devices (including newer iPhones)
  • The issue only occurs on iOS (not in preview or other platforms)
  • I am using the automated iOS export from GDevelop

What confuses me is:
Around 3–4 months ago (December), this worked correctly. The game always started directly in landscape without requiring manual rotation.

So something seems to have changed in the iOS export or handling of orientation.

This is a critical issue for me, because it breaks the first impression and also affects UI scaling and gameplay.

Has anyone experienced this recently or knows if something changed in the iOS export regarding orientation?

Thanks!
