Read Mode default
I was asked to create a document in such a way that when it gets passed along it opens in Read Mode instead of with the comment, fill &sign and more tools panel open. Apparently that can't be done.
Thanks for reaching out to us.
Looks like you do not wish to see the Right hand taskpane when you open PDF’s.
