For another, you never requested that the user be able to edit the data. Simply expecting it and hoping for it is not the same as communicating a requirement.
If you need the user to be able to edit the data in the field, it can be done, but it will take some rather extensive processing in the database synchronization step that will take time to design and develop. And that will cause the release date to be delayed, possibly by months.
Now how much did you really need that feature again?
