I am using Free version of Spire PDF and recently upgraded to the latest version 10.2.0
I know that there is a limitation of merging 10 pages in the free version and it was working fine before the upgrade.
However, after the version upgrade, it is no longer working for 10 pages and throwing a System.ArgumentException: The page already exists in some section. (Parameter 'page') at Spire.Pdf.PdfSection
It works fine for less than 10 pages but no longer working for 10 pages. Is that a known issue? Is there any recommended fix with the free version? I am using an array of streams to merge the Pdf files which is the first overloaded method:
PdfDocumentBase PdfDocument.MergeFiles(Stream[] streams)
