I get this error message: "Get this error message: "Error: The network dataset properties were not updated. [excetion from HRESULT: 0x80040301]" when using the tutorial data (San Diego Dataset) to create the Network Dataset from ArcGIS Pro.
Can you give some further details about your workflow? That error is unexpected, but there's not really enough information here for me to help you figure out what went wrong.
You're probably training to modify the properties of your network dataset.
The error occurs because the network dataset properties cannot be edited while the network dataset layer is in the map. You must remove the layer (network dataset) from the map to proceed with the rest of the tutorial.
