Acrobat Digital Signature Issue

Acrobat used to have the capability where you could add a signature with the form fill tool, save and close it, then any user that fills the form could click on the field and establish and save your digital signature and then save their document. 

Now however I click on the signature field and it just types my name as if it were a standard text field. 

Any thoughts on how to make this work for an actual digital signature for any user that fills the document, as it used to? 

I am using Adobe CC so my software is updated. 

Thank you.
