I am using the Python API to publish a web map using a hosted feature service that I published from a file geodatabase in My Content. I am following the example in the Python API sample Jupyter Notebook 'Publishing Web Maps and Web Scenes' in the '05 Content Publishers' group of notebooks. The map publishes fine, the basemap displays correctly but the features in the feature service do not show up when I view the web map in the Map Viewer. They are listed in the Details window correctly but do not have any symbology. When I click on the Legend button it says there is no legend. If I create a web map from with ArcGIS Online using the same feature service, the features show up correctly.
