Sticky Note

[hooi_sengt72622324]

Some of the PDF files I received do not allowe to insert sticky note (function disabled, apparently by the sender). How do I enable this function so that I can add sticky note into the PDF document e.g. payment information made to credit card ?

Acrobat Reader can't remove the protection.

Who can do so then, only the seller ?

Owners of Adobe Acrobat and the permission password can change the protection.
