My Arcgis pro is 2.3, the newest version, but it is too much slow. For example, chnging a symbol for a country border polygon (which I download from nature earth) will take 10+min or totally crash down. The polygon is local file, the same projection.
the weird thing is , when I use the "world countries" from Arcgis online in Arcgis pro, changing symbols seems normal again. Can anyone tell me what is the issue? Projection ? Or the Arctic pro does not recognize my local file? Thanks.
