I am unable to comment and/or highlight in the documents in PDF portfolios on my Samsung Galaxy tablet. Whenever I try to comment/highlight in any of the documents that are part of the portfolio, I get the following error message: "This document cannot be modified because it is an attachment". I am though able to highlight an comment in the exact same documents in Adobe Reader on my PC. What can I do, in order to be able to highlight in these documents on my tablet as well?
May I know the version of Android you are working with? Also PDF Portfolios use flash for navigation control and mobile device do not support flash. Files in Portfolio will be listed as attachments because of lack of Flash.

Currently, the functionality to add annotations in Pdf portfolios is not supported in Reader Mobile. We shall try to incorporate in a future release.
