I can get everything else returned except the maps. I know the page says its subject to change. Any ideas?
Seems this step might be the issue:
Enable map widget:
The ArcGIS Python API includes a map widget for embedding maps in the Jupyter notebook environment. To enable the map widget for all users, use the following command:
python -m arcgis.install
If you are on a Linux system and do not have permission to install the widget system-wide, you can install it in your local user profile by using the following command instead:
python -m arcgis.install -u
You can now start using the ArcGIS Python API in your Python IDE of choice, or the Jupyter Notebook environment.
