DirectQuery for PBI datasets and AS

Hi,

Apologies if this has been posted before!

I have enabled the DirectQuery for PBI datasets and AS option in Preiview features in the PBI desktop and have been able to connect to a PBI dataset to create visuals in my report, however when this is published to the PBI service, the visuals on the page do not display:

I have created a connection in our gateway to the relevant dataset (that is also published in the service), however still no luck.

Does anyone know what i'm doing wrong??

Thanks!
