Signers have to type in their name when I don't expect them to have to.

Hello!

• When sending a document for signature, in the recipients list, I enter both the email address and the name of each recipient (all signers). So Acrobat Sign already knows the name of each recipient.
• In the next step where we can edit fields, I only add signature fields, one assigned to each recipient.
• When the recipients do sign the document, in the signature popup, they have to enter their mobile phone number to draw their signature on their mobile device. (On purpose, I selected the option Require signers to use a mobile device to create their signature and initials as I find it provides a nice second authentication method, as it makes me able to verify the signature was actually drawn on the intended recipient's mobile phone.)
• The recipients then proceed with drawing their signature on their mobile phone, and the signature gets uploaded as expected.

What doesn't make sense to me is that, before hitting the Apply button, they actyally have to type in their name in the Name field (under the signature on the left side). I would expect this field :

• To be already filled in as I already provided the recipent's name in the recipients list.
• Not to be editable, since I deselected the Signers can change their name or initials setting (I want to avoid the document to be signed by anyone else thant the intended recipient, e.g. the intended recipient forwarding the email to his/her assistant instead of using the proper delegation function - I understand I actually do not have any control over this, but I'd rather not suggest it is possible by offering the possibility to type in any name).

How do I make sure the Name field in the signature popup is pre-filled with the name I provided in the recipients list and grayed out so that it can't be edited?

Thank you!
