[Bug]: 3D terrain does not show with Mapbox v11

Mapbox Implementation

Mapbox

Mapbox Version

11.4.0

React Native Version

0.74.5

Platform

iOS

`@rnmapbox/maps` version

10.1.29

Standalone component to reproduce

import React from 'react';
import { StyleSheet, View } from 'react-native';
import MapboxGL, { Terrain } from '@rnmapbox/maps';

export default function App() {
  return (
    <View style={styles.container}>
      <MapboxGL.MapView style={{ flex: 1 }}>
        <MapboxGL.RasterDemSource
          id="mapbox-dem"
          url="mapbox://mapbox.mapbox-terrain-dem-v1"
        >
          <Terrain style={{exaggeration: 1}}/>
        </MapboxGL.RasterDemSource>
        <MapboxGL.Camera
          zoomLevel={11}
          centerCoordinate={[7.658596832896972, 45.976536103548355]}
          pitch={60}
        />
      </MapboxGL.MapView>
    </View>
  );
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
  },
});

Observed behavior and steps to reproduce

Component above should pan to the Matterhorn, and show extruded 3D terrain. If I switch to using mapbox v10, it works. In v11, the 3D terrain is not shown. No errors or traces, neither from react / expo nor from native code in Xcode.

Flat Matterhorn

Things I tried:

Using 'import Mapbox' instead of 'import MapboxGL'
Using direct component imports
Explicitly setting the source id for the terrain
Adding and removing sky layers according to the example (the sky layer works, but doesn't affect terrain)

I have not verified this on Android.

Expected behavior

The maps pans to a beautiful 3D view on the iconic Matterhorn.

Or in boring terms: terrain is shown in 3D, not flat.

Notes / preliminary analysis

I wish I had, but since there's no error emitted I'm at a loss. Of course, I genuinely hope I just made a typo somewhere and this is easy to fix 😄

I included download and public tokens, I will invalidate these once the issue is closed.
