Google Analytics Dashboard not refreshing

Hi,

I've constructed a dashboard on Power BI Service by taking visuals from a Power BI Desktop file which I've created using Google Analytics data.

The purpose of this was to have it on a TV screen so that people can have a quick glance at what has happened on our website, without anyone needing to interact with the data. However the data isn't refreshing in the way I would like it to. I have a scheduled refresh daily for the report but from what I've read with other sources like DirectQuery you can have the dashboard refresh around every 15 minutes. Is this not possible with Google Analytics or is there something that I am missing in order to make it work? 

Thanks in advance!
