Its been a very frustrating lack of co-ordination here. We had WSfB apps deployed and available to users. We are deploying Windows 11 to our end users. As well as a change of behavour now (i.e. you cant launch the store application at all if private store only is enabled) I had issues with WSfB applications not updating, contacted MS support to be told, we wont fix or look at this it as its out of scope of support.
So using Microsoft's flagship OS (Windows 11) and management platform (Intune) and I'm now removing WSfB applications and replacing with traditional Win32 packaged ones again
Why the existing functionality could not at least be maintained until the replacement was ready? Its even worse when later you see they backported the Windows 11 store app to Windows 10, still supporting the private store, but on 11 doesn't support this functionality
