I use my Apple Pencil similar to a mouse normally so I do not smudge up my IPad. When I open a PDF as an email attachment, the Apple Pencil immediately draws on the PDF rather than letting me move the PDF as if I was using a mouse. I would rather turn draw on when needed rather than having it automatically on. I do not know how to turn draw off within an emailed PDF. I do not know how to turn draw off as a default?
