Hi Andy,

The mileage tracker will only be available on the app for Master Admins, therefore you won't see the controls for this. 

Auto-tracking can only be enabled on the device which the MA is signed into, so it would be recording their own journey, not any other users on the account.It's not possible for the MA to locate a different user using the tracker. 

Please get back to us below if you have any questions, thanks!
