In VR, while it is still possible to drag and pan with mouse the overall maps, it’s not longer possible to drag and pan with mouse in VR the Jeppesen charts. Anytime when you want to zoom on a part of the chart you must unzoom to the entire chart page view and the zoom on a particular part of the chart. You can’t just move the chart with the mouse in VR.
This regression was probably introduced with the Rogers Data maps.
