I completed first 2 exercises in Chapter 3. Exercise 3D Connect spatial datasets is my stopping place. The IL_food_deserts.lyrx is the problem. Has there been a problem with the exercise data files that were downloaded?
I skipped to Chapter 4 Creating and editing spatial data. Exercise 4a was fine until I started Map x,y points At step 4, the coordinate system was different from the example.
I have a free trial that came with the book for 180 days. I downloaded ArcGIS Pro 2.9.
