Windows Hello for Business and Windows Admin Center

Question

We have just recently implemented Windows Hello for Business in our domain through Intune/Endpoint Manager and GPO using the key trust model and it seems to be working fine for workstation logons but are having trouble authenticating with our WAC gateway.

When we try to complete the Windows authentication to the gateway using a PIN or other Hello credentials, the authentication fails but using the same account with a password does work. So far, I haven't been able to locate any events on the client, domain controller or gateway server that would further explain what is failing but my assumption is that it is with our Hello setup.
