Lacking some features

If you have a Google Apps For Work account, you can set up resource calendars for shared locations and objects (like meeting rooms, cameras, projectors, cars in fleet, etc).
The iOS version of Google Calendar isnt able to access these resources, so you cant book a meeting in a shared meeting room.
I hoped thered be better integration between Google Calendar and Google Apps for Work.
