Hi;
First I need to clarify what your workflow was - what exactly did you use to fill out the PDF? There is a "Fill & Sign" website, and a "Fill & Sign" panel in Adobe Reader... Were you using the "Fill & Sign" tab on the website https://cloud.acrobat.com/fillsign to fill out the form? Or were you using Adobe Reader and the "Fill & Sign" tools?
Thanks,
Josh
