Additional Information

This issue was determined to not be a bug in Collector, but rather a matter of mismatched spatial references between the webmap item and the updated basemap that was performed using the ArcGIS Python API. This mismatched spatial reference was causing the basemap and operational layers to fail to render in Collector. This issue can be addressed in the Python code by updating the webmap spatial reference to match the basemap via the webmap's data dictionary. In this case the webmap's SR was 4326 and the basemap SR was 32611. In addition to addressing this issue in the Python code itself, if the webmap were to be resaved via the ArcGIS.com Map Viewer, it would also correct this mismatched SR issue and allow the map to open successfully in Collector.

Workaround

Navigate to the Basemap Gallery and choose the default basemap and the default basemap renders as expected.
