Hello,
ServiceM8 does not archive the GPS location data per user, only the "live" location.
We have looked at different options for this, such as a solution which would record these locations at set intervals, but this is dependent on the staff member's device being configured correctly for Location Services.
We have moved into a different direction and are developing an integration with a Fleet Management solution which will provide better and more accurate data based on appliance hardware in the vehicle rather than relying on the user and their device settings.
