Defender Firewall - rules configured in Intune not applying on Win10

BillB_Venzo I spent\wasted pretty much my full day today working this out. Finally, i got it working for us.

Our devices are Azure AD joined only. and when I was configuring the firewall rules, I was selecting all the network types (such as DOMAIN, PRIVATE, PUBLIC). Seemed like it didn't like the DOMAIN selection as the device is not joined to any DOMAIN (in a classic sense). When i removed the DOMAIN from the network types, it was successfully applied.

Once successful, your rules should appear in:

Control Panel\System and Security\Windows Defender Firewall\Allowed applications

I still have two issues:

1. Why are these firewall rules not appearing in Advance Settings --> Inbound rules (if it is an inbound rule)

2. In Allowed applications, i saw the rules appearing but the PUBLIC and PRIVATE networks weren't selected. 

But when i actually tested the firewall rules (my firewall rule is to allow JAVA.exe) and it works.
