[SalesForce] Can you edit work orders in the field service app

I know you can edit records (including Work orders) in Salesforce1 but when i am trialling Field Service I cannot edit a Work order.

My user is now set to the System Administrator profile so I can't believe their are missing permissions.

The documentation states with the app you:

The mobile solution provides access to critical information regardless of connectivity, and uses automated processes to support a
full range of fi eld activities, from sending and receiving real-time
job updates to managing work orders and speeding up manual
administrative work. It even enables users to generate reports,
access knowledge articles, update parts required, and capture a
customer’s signature.

It states "managing work orders" as a feature but I can only see features for creating a service report, a new task, opening in salesforce1, adding to the feed and getting directions.

Thanks
