A Drone2Map for ArcGIS license file generated from My Esri overrides ArcGIS Pro licenses when authorized on ArcGIS License Manager 2018.1. The licenses override one another, allowing only one to be used, and not both. This issue only occurs with license files containing a media access control (MAC) address.
The content of the Drone2Map for ArcGIS license file is incorrect, causing the license manager to read Drone2Map for ArcGIS licenses as ArcGIS Pro licenses. When authorizing using this license file, the license manager overrides existing ArcGIS Pro Named User licenses in the service.txt file.
