I work with a local clinic and we want to be able to send out a form so that a patient can electronically sign it instead of waiting for it to be sent in the mail. I can receive the document on my phone and computer but I can only sign it on my computer. I literally just reinstalled the latest version of Adobe Acrobat Reader onto my computer (Windows 10 Home) and HTC One M8 Android phone so I know it's not out of date. I can sign other documents on my phone. Would there be a reason why the same document won't let me sign on the phone but just my computer?
Additionally as a side note, slightly unrelated, are there any versions/types of Adobe Acrobat and Adobe Acrobat Reader that don't allow someone to electronically sign?
