Frequently asked questions
Why don't I see my comments, form data, or signatures in my PDF?
It may be that you are not using Adobe's Reader. Other PDF viewers such as Apple Email may not support all the features that Adobe's Reader supports. View your PDFs with Reader, and if you send it to someone else, encourage the recipient to do the same.
