Help configuring digital signature?

I've recently been upgraded to Acrobat DC Pro. In my previous version, digital signatures included text that indicated that I had digitally signed the document on a particular time & date. I can't seem to make that work now, even though I can see a signature that looks like that in "Configure Signature Appearance" in signature settings. I have a Digital ID for which I've checked "use for signing" in Digital ID & Trusted Certificate Settings. All I get when I select the "Sign & Fill" tool is my typed name. What am I missing?
