Communicate within your own company about New things and when things don't function

I definitely think there is a breakdown in communication within your own company in regards to new things that are added and things that don't function. Just today I was looking through a user guide from TruLearn that was updated just yesterday to see all the things listed under "What's New" and I found a new feature that I was interested in so I went into the Table Maintenance and tried to enable it and the checkbox didn't work so I put in a Situation with your support to ask about it and was told "That is not a functioning feature, it was added a while back but does not workunfortunately, which is why you are unable to click on it." so why did the newly updated user guide from yesterday claim it does work?? The people who create and upload the user guides are apparently not kept in the loop on what stuff actually functions or not and that is sad and confusing for your customers.
