@jsimon_1 We actually created a simple workaround that temporarily disables our internal WSUS settings to allow Microsoft Store apps, and then reverts back to our internal settings when you're done with the MS Store.
There are two .reg files to turn the Windows Update internal settings on/off:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU]
"UseWUServer"=dword:00000000
The 0 dword value will ignore any other WSUS registry customizations for accessing an internal server. Our other .reg file is the same thing, but dword value of 1 to change back to using internal WSUS settings.
Then we have a batch file to stop the Windows Update service, change the registry keys, and restart the service.
CLS
@ECHO OFF
color E0
net stop "Windows Update"
REGEDIT /S "%~dp0ExternalWSUS.reg"
net start "Windows Update"
CLS
ECHO.
ECHO Windows update settings have been unlocked
ECHO ------------------------------------------
ECHO You can now check for Microsoft Windows Updates and/or use the Microsoft App Store.
ECHO Un-Pause to reset.
ECHO.
PAUSE
CLS
color A0
net stop "Windows Update"
REGEDIT /S "%~dp0InternalWSUS.reg"
net start "Windows Update"
CLS
ECHO.
ECHO Windows update settings have been reset
ECHO ---------------------------------------
ECHO.
PAUSE
It's an extra step to remember or train users on, but we weren't able to find any other way to allow both internal WSUS -and- Microsoft Store at the same time.
