I have created an Android app and followed the instructions within https://developer.android.com/work/managed-configurations to set up Managed Configurations, as this app is intended to be deployed via an MDM/EMM using Managed Google Play.
However, when I upload the app it doesn't appear to recognize that the managed configuration has been defined, as when I attempt to create an App Configuration Policy within Microsoft InTune it isn't showing the specified configurations.
As an example, when I look at the Adobe Reader entry within Google Play work, I can see an entry for "This app offers managed configuration", however that is missing in our app.
Is there anything extra necessary to complete, aside from the details in the link above, in order to ensure that the Managed Configurations are available for an MDM/EMM to utilize?
