Company portal failing to install error 0x87D1041C

Hello,

We have seen the error when when the ASSIGNMENTS for the UWP Package Company Portal is USER and DEVICE mix at once (BOTH/MIX).

Microsoft KB states that for UWP packages you should ASSIGN the package to device group. 

This is from the concept like an MSI ALLUSERS settings which will install the MSI package to all user profiles on the machine installed under system account agent (With traditional software Deployment)

We had solution from here:

Microsoft Store UWP apps

In addition to user context, you can deploy Universal Windows Platform (UWP) apps from the Microsoft Store app (new) in system context.

If a provisioned .appx app is deployed in system context, the app auto installs for each user that logs in. If an individual end user uninstalls the user context app, the app still shows as installed because it's still provisioned.

In addition, the app must NOT already be installed for any users on the device.

Our general recommendation is to not mix install contexts when deploying apps.
