I downloaded a geojson file include all nations area, I loaded the data using Cesium.GeoJsonDataSource.load, the polylines showed, but can not play the animation on clock widget (nothing happened after play button clicked). The other regions are good. I think the reason is when rendering ATA region, the longitude goes negative from positive. Hope someone can help me fix this issue.
Here is the Geo Json file
