Fill & Sign doesn't work with Forms created by Acrobat Pro

I have created a PDF form with Acrobat Pro.  I am trying to sign the form with Fill and Sign and regrettably Fill & Sign doesn't see the form data that has been populated by Acrobat Forms.  I'm not sure if this is a bug with Acrobat Pro or Fill and Sign.  I've seen others post similar questions where the Adobe team seemed to say the culprit was Apple Preview for PDF.  In this example, its two Adobe products (no Apple Preview) which don't talk together.

I have found a "work around" (if you can call it that) where I have to save as Optimized PDF in Acrobat Pro (which breaks the form) but at least I can sign it....

Does anyone know of a workflow where one can take a Form created in Acrobat Pro and open it (with form data) in Fill & Sign?
