You are running one of the Mileage reports but it does not pull any data for a worker.
This issue happens when the worker's device is not tracking or cannot upload the location data to the StreetSmart server.
Refer to the article GPS Location Tracking Is Not Working on Device to identify the root cause of the issue and resolve it.
Run the corresponding Mileage report again - it should contain the data for the required worker.
