I was trying to upload the KML file to my Content in my AcrGIS online account. However, I received an error that it cannot be uploaded do to the long time of uploading. Does somebody know if there if there is some limit for KML files like it is for Shapefiles (up to 1000 Shapes)? I am not sure if the number of Shapes in KML is here a problem, or just the the time which is needed to upload this. I have more that 1000 Shapes in my KML file.
