Yes they are the master admin, if its the case that the master admin can use the mileage tracker but standard users cannot why is this the case. Its more likely that a standard user will use the mileage tracker. 

Also got a friend who uses the QB's online app, he is a standard user and can use the mileage tracker...

Tim, apologies for jumping on your thread but the issue is that it can be used currently in the standard app as QB have made mileage tracking available to all types of subscriptions.
