Unable to logon using Dell WYSE terminals

Hi all,

I'm having an issue logging into AVD from Dell WYSE terminals. I have created a dynamic host group and added a service principal for them per guidance from Microsoft, and that has fixed an issue where the permission granting pop up was not displaying.

After that, logon works fine with the web client but it will not complete sign-on with the Dell WYSE client.
I have found the following errors in Azure AD but at a loss how to resolve as I have already added a service principal to the dynamic groups for hosts and unable to add a service principal for Windows Virtual Desktop AME.
