I'm sending a doc out for signature to 2 separate people. Doc is only allowing for 1 signature. what am i doing wrong
As you have mentioned that you are sending documents to 2 separate people for signature, do you mean that you are sending the form to get signature from 2 people on a single document?
If that is the case and you send the document using Adobe Acrobat DC or the Adobe Sign, you need to assign the fields in the form for each one.
Please take help of the steps mentioned here Assign form fields to recipients
When you do not assign the fields in the form, the PDF from gets locked once a signature added to it.
That is the reason the second person is not able to add the signature.
Let us know if you need any help.
