Replying to the other post, suggesting replacing "/homepage" at the end of the URL for the blanked page with "/?useAppfabricSPA=false":

Great idea!  And it works - but only up to a point.

When you get to the "Learn more" at the "Moving to QuickBooks Desktop?" question, it takes you to a help page about exporting via Excel, not to the next step in what used to be the usual direct export to QBDT process.

Looks increasingly like they really don't want you to be able to do this any more.  Makes no sense, because they make money anyway (unless they are afraid that QBDT is a superior product to QBO).

Bad news -- but thanks for the tip!
