I have inserted two SignatureFields and when I try to sign the pdf with the second signature i got this error message:
class com.aspose.pdf.exceptions.PdfException: You cannot change this document because it is certified.
Im using the demoversion 21.10 of Aspose PDF. Are there some limitations inn the demo?
I can not find any examples on how to solve this.
Could you please share your sample PDF document(s) along with complete sample code snippet so that we can test the scenario in our environment and address it accordingly?
