Hi Rick,
Did you try attaching screenshots to your reply to the email from this forum? Because the Adobe forums do not accept any type of attachments for security reasons, your photo attachments did not get through. Sorry about that.
But I think I know what you saw when you tried to open one of the PDF Application Forms on the Alberta (Canadian) government web site.
Did you see a message like this in Safari on your iPad?
Please wait... If this message is not eventually replaced by the proper contents of the document, your PDF viewer may not be able to display this type of document. You can upgrade to the latest version of Adobe Reader for Windows®, Mac, or Linux® by visiting http://www.adobe.com/go/reader_download.
If so, the PDF form is a special type of form called a "dynamic XFA form". The message is displayed when a dynamic content is not supported by a PDF viewer.
As far as I know, there are no iOS apps that support dynamic XFA forms. The mobile version of Adobe Reader does not support dynamic XFA forms. Neither does Safari or iBooks on iOS. It's the limitation of mobile PDF viewer apps.
To recap
- Dynamic or static XFA forms - Use the desktop version of Adobe Reader or Acrobat on a Mac or Windows computer.
- Most PDF documents and non-XFA forms - Use the mobile or desktop version of Adobe Reader.
Please note that Apple iOS apps (such as Mail, Safari, and iBooks) do not display filled form data or annotations (sticky notes, highlight, etc.) at all. If a PDF document/form is first opened in Mail, Safari, or iBooks, you need to use the iOS "Open In" feature to open it in Adobe Reader for iOS.
How to open PDF documents in Adobe Reader for iOS (iPad on iOS 7 or 8 version)
(This is the same FAQ document that I mentioned in my reply #2 above.)
In this particular case, using the "Open In" feature to transfer the PDF Application Form from Safari to Adobe Reader for iOS does not help. Because Adobe Reader for iOS cannot display the dynamically generated content of the XFA form from the Alberta government web site.
But you should be able to open other "regular" PDF documents (just like the one that I provided as a sample link) in Adobe Reader for iOS.
Hope this helps. Please let us know if you have additional questions.
