Catalyst app localized languages other than base language (EN) not being displayed in Mac App Store

Our macOS Catalyst app is localized for four languages: English (Base), French, Spanish and Chinese (Simplified). This all works fine during testing. However, when the app is uploaded via Xcode to the App Store, it only shows “English” in all of the areas where languages are displayed. For example, on the Mac Build Activity building information page.

Only “EN” is also shown in Mac App Store app.

This all works correctly in iOS App Store with same build, archive, upload steps.

Has anyone else noticed this problem and if so, have you found a solution?

Ran into the exact same problem. My app uses Simplified Chinese as the base language and also supports English. But on the Mac App Store page, it only shows that Chinese is supported. Yet when I download and install the app, it does support both languages. You can even verify the list of languages supported by the app through System Preferences -> Languages & Regions -> App.

So this means there should be no problem with the app build and the problem is with the Mac App Store.
