OTA update creates new Expo app but doesn't update App Store app

I’m a new Expo user and working with a pre-existing codebase that already uses Expo and has a live app published to the App/Play Store.

I made some small changes and ran expo publish, which created the app at Expo but I’m wondering how to get those changes reflected in the standalone app currently published in the App/Play Store. I’ve been added to the dev team account in App Store Connect and Google Play Console but am not sure where to go from here?
