Highlighting/putting comments on restricted use pdf

[Polly 0]

I have some pdf's which are "restricted use" and I wanted to highlight and put comments in for my own records.   Is there a way to do that?    Thanks!

In order for me to further assist you with your concern, I would love to get a copy of a restricted PDF file so I can check it on my end.
