hunk.code_window: Since `exp build` does not apply to ExpoKit projects, you can edit the native project's release channel manually by modifying the `releaseChannel` key in `EXShell.plist` (iOS) or `Constants.java` (Android).
   ## Notes
   `expo.manifest.releaseChannel` does NOT exist in dev mode. It does exist, however when you explicitly publish / build with it.
