features dont work
i would like to split page but every time i get the error message
( you cant change the security of the document because the document is signed or certified )
i would like also to add my signature but cant because the add signature button is not clickable at all,
Thank you for reporting the issue. We regret you facing inconvenience.
Seems the PDF documents have restrictions w.r.t page extractions and signing operations. Please check Document Properties (CTRL+D or CMD+D) > Security and see if any document security is applied.
If you are not the author of the PDF, you will need to contact him/her to.
Please share the version of acrobat you are using. You can do so using the link -helpx.adobe.com/acrobat/kb/identify-product..
And also share the test PDF file using forums.adobe.com/docs/DOC-7161 for us to investigate further if this does not resolve your issue.
