Does Zoho docs show edits made by each team member on a shared document so we can tell who changed what?

Does Zoho docs show edits made by each team member on a shared document so we can tell who changed what?

My team is currently working on a document, soI uploaded the draft and shared it with them.  When one team member made changes, I don't see any marks to indicate that changes were made by him rather than by someone else.  How do we keep track of which members made which changes to a document? All I could see was that someone made an edit to the document at a certain date and time.  Because I'm not sure what he changed, I don't even know if the changes made it into the document - maybe he just changed one comma, and I'd never spot it.

The point is - we can't see who's making what changes as we edit the document.

 Are we using this wrong?  Or is that just the way Zoho works?
