... in the mail app of an iPhone.
Apologies if this is a sore subject, but....
I am testing a simple form that is submitted as a PDF, and emailed as an attachment. On a desktop, the attachment opens and all the submitted data is shown. On an iPhone, the form shows nicely but all the submitted data is missing.
Is there a fix or a workaround to this, or is it just an Apple vs. Adobe issue that we'll have to live with? Perhaps there is another way to create the PDF attachment?
I used a generic button (not email or http submit), then chose submit for the action and selected PDF as the submit option. I also made the submit URL a "mailto" email address.
