Digital Signatures do not appear

[vilnios]

When users are e-mailing an institutional form that contains digital signatures, the signatures disppear when the file is opened in Adobe Acrobat. Some troubleshooting I have done are below.

Windows 10 computer, Outlook Web App (OWA) and Microsoft Edge:

• When previewing the file within OWA, signatures show up
• If I download the file and save it to my desktop:
  • Open the file in Adobe Acrobat Reader (v2019.021.20061), signatures disappear
  • Open the file in Microsoft Edge, signatures are present
• If I print the file using 'Microsoft Print to PDF', then open the file, signatures are present but the form fields are now lost.

On a MacBook Pro running macOS Catalina 10.15.4

• Outlook Web App to preview the file
  • Using Mozilla Firefox, no signatures
  • Using Edge Chromium, signatures appear
  • Using Google Chrome, signatures appear
• Download the File and open using the indicated app
  • Apple Preview App, signatures appear
  • Adobe Acrobat Professional (v2020.006.20034), no signatures

I am guessing when the signatures are appearing, the file is being previewed in a "flat-file" format. However, why are the signatures disappearing when I open the file in Adobe Acrobat Reader or Professional?

Hi there, we are having the same issues more or less. We have a form in which 3 digital signatures need to be added from people with different functions. They all appear simultaneously if I open them on Acrobat Pro on a Macbook but only the most recent one appears in Acrobat Pro on a Windows computer. Signatures appear again if you print to PDF.

However, this isn't good enough as I keep getting emails from people with Windows computers thinking there is a problem when in fact the signatures are there, just invisible? Very annoying!

Also why is there no print to pdf functionality available on Macbooks? Really can't understand how a company the size of Adobe cannot make software that works the same on different operating systems, honestly it's 2021.

It's 2023 here, and I am facing the same issues. Disappointing! I am going to start searching for open source alternatives now.

Can you share such a file? It can be a dummy file, but it needs to reproduce the issue on your side.

Hi there,

I'm having exactly the same issue, do you have any suggestions to solve this ? 

All the ''solutions'' i've seen so far didn't actually help.

Thanks!
