Ive made a square box ,made the keyline black and the fill white, turned it into an interactive tick box. Then I make the PDF and the tick box just appears as the blue shade to fill in not with a keyline box. Any ideas why? Thanks.
Thank you for reaching out and sorry for the delay in response. I am unable to reproduce the issue at my end on a windows machine. Is it possible for you to share a video or screenshot of your workflow for better understanding?
