A Python API script runs without error but fails to enable offline mode for a hosted vector tile layer in ArcGIS Online.

Solução Provisória

In ArcGIS 3.5.x, change the script to use the arcgis.mapping module instead of arcgis.layers. The script runs successfully in the Python window without any error or warning. Refreshing the layer’s Settings page in ArcGIS Online confirmed that offline mode was successfully enabled.
