Do you have problems in both deploying your .pcg package and deploying any AE profile policies?  Have you done any tests on devices of other brands/models or different Android firmware versions?

Is it possible that you tried to deploy a classical Android+ profile to your Android-Enterprise devices?  Please note the confusion in the terminology used in the web-console GUI/documenation since v14.x.  Android+ was previously used to refer to the devices using OEM specific device agent but has since v14.x been used to refer also, if not more, to devices using the OEM independent Android-Enterprise device agents.  

In general., the .pcg.packages generated for "Android" platform by Package Studio works for both Classic Android+ and Android Enterprise devices.

Without more details, it is hard to judge if your current problem is related to the v14.1.5 MobiControl server /Package-Studio version, or to the way you configure/install the server.  

Thank you Raymond.  I fiddled a little more and I am actually successful delivering the profile.  So that's not it - I made a simple platform to set the WIFI up and it did work.  So it seems like it doesn’t like my app.  I am able to install the app APK myself manually.  Further, when I try to force package reinstallation the message which is terse says "Failed to Install (Incompatible Platform)"

My guess is that something is blocking this - I have no other profiles on GMS devices, all are non GMS.  I wonder if google play is somehow preventing this, or the app is not registered with google as a private app?  I do have play protect off. These companies are somewhat hands off with IT (smaller companies) and I am trying to give them a truly managed solution.  I wonder if I should look to sideload the APK maybe via a script or some other method?
