1803 Windows app privacy permissions via Group Policy

Hello, 

We are using the GPO settings under Administrative Templates > Windows Components > App Privacy to control access of Windows store apps use of various system resources such as the Microphone (Policy Name: "Let Windows apps access the microphone"). 

Since the 1803 update, if we enable a policy to control the camera or microphone it impacts all other (non-store) applications installed to the system, such as Skype for Business. This behavior is different to 1709 which allows control of the store apps (even on an individual basis), but leaves the other non-store applications without restriction.

How can we configure this setting without impacting non-store applications installed to each system? 

Steps to recreate the issue (assuming a built in mic to the system):

1. Update to 1803
2. Configure the Administrative Templates > Windows Components > App Privacy > Let Windows apps access the microphonepolicy and set to Enabled with Force Deny as the default. 
3. Open the Sound settings control panel. You will see no levels.
4. Open a non-store application and test (e.g. Skype for Business). 

Thanks in advance for your help.
