Issue: Digital signatures in a PDF file created using a PDF editor are getting removed when setting up a signing task on the portal.
Cause: This issue arises from the PDF containing multiple layers of content/data, with the signature content residing on a distinct layer separate from the main document.
Workaround/Resolution: To resolve this problem, the PDF file must be flattened before uploading it to the portal to prevent the additional (signature) layer from being removed. Below are a few links that provide instructions on how to do this using different programs:
