Hi,

 

I've configured Windows Virtual desktop using the new release but having issues login into Remote Desktop app after clicking on 'Subscribe'. I get an Error CAA20004 and 'we couldn't authenticate you.

 

However I can access everything via the Web portal (e.g. full desktop or published apps).

 

My setup is: 1x WVD session host joined Azure AD domain services, M365 E5 licenses. 

 

I happens to all user accounts.

 

Any ideas? Thank you.

I fixed the issue by adding consent to the WVD app.  It was missing from the Spring 2020 documentation.  Check out the steps to fix the issue below
