Using LiveCycle I created a form with expanding text fields and saved it
as a PDF. I enabled user rights in Acrobat. It opens/works fine with
Reader on Windows 7. But I cannot open the form using Acrobat DC on my
iPhone. I have an Acrobat DC for Windows subscription and signed into
Acrobat on my iPhone. But I get this error: "This form requires adobe
acrobat reader dc for mac or windows." Is the problem that I need a
subscription for Acrobat on Mac?
