Question of the IT Director to the IT developer in the work correspondence:
What does “as far as I know” mean? Does the object not work as planned?

Answer from the IT developer:
That means there are things I know they don’t work as they should. But that doesn’t mean that the things I know are working wrong are all things that are working wrong. It is possible that there are other things that work wrong, but I don’t know about them. I just try to avoid categorical statements that there is only one problem left, because. It may not be so.
