Adding a Read Only User to Hyper-V Cluster / Access is denied

I am trying to add a user with "read only" permissions on a Hyper-V cluster. I'm logged into one of the cluster host servers and I ran the following Powershell command: 

Grant-ClusterAccess -User contoso\johnj99 -ReadOnly

I can look at the properties of the cluster, Cluster Permissions tab, and see the permissions I granted there. However, when I log into the same server as that user and open Failover Cluster Manager, I get an error that the user cannot connect with the message "You do not have administrative privileges on the cluster." with Error Code: 0x80070005 Access is denied.

What am I missing here?

    Hi,

    After run the command above to grant the user read-only access, the read-only access user can connect to the cluster via PowerShell only. Attempting to connect with the Failover Cluster Manager will result in an error: Error Code: 0x80070005 Access is denied.

    For more information, please review this link below:

    Hello,

    So is there a way to grant read-only access to Failover Cluster Manager, or no?

    Hi,

    I'm afraid there is no GUI method.
