I've just got our field guys to start using Fabrication Review. The biggest complaint I'm hearing from them is that they can't make comments and give a proper "Review" of the content. Even if they were able to place comments and save, then send it back to us.
They can "see" a lot of things with Fabrication Review; but if they want changes then they have to use another software to get the changes to us. Like screen capture, or type out an email.
