[GNC] How to determine why my QIF import is failing

[Chris Velevitch]

I'm running v3.5 on macOS 10.13.6.

When I import a file, I get "Failed" and according to the to QIF Import dialog:-

     When you press the Start button, GnuCash will import your QIF data.
     If there are no errors or warnings, you will automatically
proceed to the next step.
     Otherwise, the details will be shown below for your review

Where can I find these details?
