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

Question on the current RLS functionality in the preview, running into some issues when testing. We have an ex. 'Parent Dataset Test' with 'Parent RLS Test' RLS role currently applied. Published to the service, applied the role, added the needed AD Group to the role, everything works like normal off any visualizations connected to 'Parent Dataset Test'. We then have 'Remote Dataset1' connected to 'Parent Dataset Test' added in 'All Measures' table and converted the connection to DirectQuery to create the local model. Published 'Remote Dataset1' to the service and no data is visible. "Couldn't load the data for this visual. The following system error occurred: (this is blank). Is the RLS rule from the parent dataset currently supposed to flow through to the remote dataset or is it unavailable for now as a preview limitation? Or is there something that needs to be done in the service to push the RLS roles?
