App icons not updating in EAS preview build

Summary

Description:
I updated my app icons in my Expo project:

• iOS app icon
• Android adaptive icon

Locally, everything works fine:

npx expo prebuild
npx run:ios
npx run:android

The icons show correctly.

However, when I run an EAS build using my preview profile:

eas build --profile preview --clear-cache

…the app icons remain the old ones.

Managed or bare?
