The verbiage you used is correct, it is a "Fundamental issue"  for accounting software.

QB is not a beta version of a free up and coming software but a paid subscription service for an established platform. The solution to your clients should not be - 'just upload it manually until we figure it out, if and when we get to it'.

This issue has dragged on for 2 months now, and shows a complete lack of consideration for QB client base. Unacceptable.
