Can't add comments to saved PDF

Question

I regularly have to comment on PDFs sent to me by a company I work with. I have the latest Adobe Reader but encounter this problem: after commenting and saving the doc, when I reopen it I can't add any more comments but get the error message in bold. Is there any way around this issue?:

This document enabled extended features in Adobe Acrobat Reader. The document has been changed since it was created and use of extended features is no longer available. Please contact the author for the original version of this document.

Hello doradiva

As per the description above, you are getting the error message "This document enabled extended features in Adobe Acrobat Reader. The document has been changed since it was created and use of extended features is no longer available. Please contact the author of the original version of this document. " while adding comments on a PDF, Is that correct?

Please refer and try the solutions from the following KB doc which discusses the similar issue and scenario Getting error messages when trying to reader enable documents. (Acrobat Reader PDF Forms) Link: https://answers.acrobatusers.com/Getting-error-messages-reader-enable-documents-q157180.aspx
