Hello dear all, thank you very much for your input! I will assign to watch the created issue
What did I do to create the file: I grabbed the original test PDF/A File. Signed it once and saved it (actually it is automatically saved as a new file with Acrobat Reader DC that I use). Afterwards I grabbed the second file and signed it again and saved it again as a separate file. I attached all these files to the issue. Best regards, Maya ________________________________________ Von: Tilman Hausherr [[email protected]] Gesendet: Samstag, 22.
