An update has just been released. Should be in AppStore shortly. In addition to fixing downloading NOAA winds aloft data, the update includes changing the way the drop-down menus work when selecting runways, SIDs, and STARs, as well as a better representation of Arc to a Fix and Radius to a Fix procedures on the map. Also, if you are connected to X-Plane on the ACARS panel, tapping the plane icon will show estimated V or reference speed for the current weight.
