Adobe Acrobat Pro - fill and sign tool signature not working

Hi NORMAN5D52,

Thank you for reaching out and reporting this.

We are sorry for the trouble caused by this issue. Could you please confirm if the issue started recently?

Please try once removing the signature files from the following location: %appdata%\Adobe\Acrobat\DC\Security\

Delete files:

Check if that helps.

If the issue still occurs, please collect the logs for the issue using the diagnostic tool and share the log ID with us.

Let us know if you need any help.
