After reading through all this, I think one simple fix to a Cakewalk response would be to replace "working as expected" with "working as
intended." People can have different
expectations of what something would do, but only Cakewalk would be 100% sure how something was
intended to work. If there's still a problem after finding out the function works as intended, then the logical follow-up would be to discuss whether a function operates as people expect.
