Difficulty with Client Signatures

[mtroop98]

Over the last few months, more and more of my clients have a hard time signing my documents. I haven't changed anything on my end. I'm not sure what the problem is because I can't see what they are doing. They can fill everything out, except actually sign the document. Also, is there a number to call someone for assistance at Adobe? I keep being sent in circles to try to find some type of contact information. 

Thanks in advance!

Are you sending the document out for signature to your clients or is this just a form that you're emailing?

[mtroop98]

I'm sending it out for their signature through Adobe Sign.

Are you adding a signature field to the document?

Yes, one has been added.

Sorry, I have two logins, one for school and one for my business. So mtroop98 & Marianthy are both me.
