Watch Face isn't recognised as a standalone app by Google Play store

I am developing a watch face using the Watch Face Format. My watch face consists of a Wear OS bundle (the watch face itself) and an optional companion app for the mobile phone.


I have set my watch face to be a standalone app (following the instructions from the
https://developer.android.com/training/wearables/apps/standalone-apps) by setting the com.google.android.wearable.standalone meta data in the manifest.xml:










However, for some reason Google Play still thinks that the Wear OS bundle is a non-standalone app (see the "Requires mobile app" message in the screenshot below).


Has anyone experienced a similar issue? Do you guys have any ideas what could be wrong?
