Share your thoughts on DirectQuery for Power BI datasets and Azure Analysis Services (preview)

Currently connecting to AAS live and it works in PBI Desktop and PB Service.  When I change this to Direct Query so that I can do more with the model by adding new measures outside of AAS, it works in PBI Desktop, but I get a "Cannot Load Model" in PB Service.
I had someone someone check to ensure the endpoint is active, along with live connections in the Tenant settings are active.  Any thoughts on what else this could be?

This is holding up a project for a client.
