ArcGIS touchscreen gestures/functionality

Hi,

Ive created a basic visual using arcGIS Maps for Power BI. The visual works fine in Power BI desktop. 

However ive published it to the Power BI service/cloud for use on a large touchscreen. The visual loads fine with colours and data but I cannot use any touchscreen functionality/gestures. I want to be able to "pinch" zoom and drag the map to navigate around the visual - just like in the desktop.

Any suggestions/solutions?

Thanks in advance!
