I cannot mark or comment or do anything else to a certain PDF on my PC.
When i clik file --> properties --> security, what I am shown is that commenting, signing and a few other things are "not allowed", the main option of "security method" just says "no security". If that was that case, I should be able to change what is allowed and what is not allowed. but I do not see any buttons that would allow me to allow editing, commenting etc. How can I do that?
The very weird thing is that if I open the document in my mobile app (it is a adobe document cloud PDF) I can edit it just fine (on multiple devices), but not on my PC.
