I have more than 500 barriers (close to 2000!). For this analysis to work, I cannot remove any of them. I was told by multiple people, including ESRI representatives, that a Streetmap Premium license would allow me to exceed the limit, but I am still getting the 030095 error. The license is showing up in ArcGIS Pro as active, but I am still getting the error when I run Network Analyst. I have tried downloading and connecting the network data that comes with the license, but am still running into trouble.
