Ok, so American express looks like they are no longer providing QBO of QFX files for download. I spoke to thier customer support, and they said it is a known issue with no timeline in place for a fix. Contrary to the instructions given by support, you cannot download transactions via csv or xls to desktop. This said, all desktop users are now at the mercy of AMEX. Please call AMEX and voice your concerns and hopefully they will expedite this.
