Expo Publish not updating React Native App

We've created a webview app and we are using Expo RN. We have done EAS Build -p ios & EAS Submit -p ios.

We have then submitted it to the app store and it is now live on the app store.

But when we make a change with the app, and run Expo Publish, the app doesn't update. I've read so many docs but I'm struggling to see what I've missed.

Any help would be great!
