I am having an issue where I am looking to apply GlobalSign AATL approved PDF signing certificate to a document that has already been signed via DocuSign. After applying the GlobalSign certificate, the PDF will generate an error on the original DocuSign certificate with the following error:
Error during signature verification
Unexpected byte range values defining scope of signed data.
Details: The signature byte range is invalid
Keep in mind that I do not have any errors with the subsequent GlobalSign AATL certificates that I have applied (see screenshots).
I am running Adobe Acrobat Pro DC version 2022.001.20142
This previously worked for me about 2 years ago but I don't know what has changed since then. I also tried using different signing formats to see if it would make a difference, PKCS#7 and CAdES equivalent but I still get the "The signature byte range is invalid" certificate error whenever attempting to sign an already previously signed DocuSign PDF document.
