Hi,
I'm using Adobe Acrobat 9 Standard.
I hide a few parts of the PDF using a blank stamp (Tools-> Comment&Markup-> Stamps -> Dynamic -> Blank). Afterwards I locked the PDF using a password (Advances -> Security -> Encrypt with Password) and I restricted permissions so no changes are allowed in the document.
When I open the PDF on my PC or using an Android phone- the hidden parts remain hidden and you can't change or move the blank stamps (unless you have the password and you unlock the security).
But when I try to open the PDF using an IPhone – the stamps move to different parts of the document, even if you don’t have the password. It means that information that I didn’t intend to expose gets unveiled.
Could you please check the bug?
Thank you.
