I too have a few apps that do not show bundled settings. I think they basically need to add support for OEMConfig. I was going to put in a feature request for it today since I didn't see much out there on it.
Not many EMM's have this enabled for Android at this moment. Actually, they don't have it for iOS either, but I suspect the apps published this past month will provide the impetus for them to get the api's loaded soon.
