When I merge 2 Pdf using the Join tool, then the existing bookmarks are lost.
Details :
Pdf 1 as bookmarks and notes.
Pdf 2 as no bookmarks nor notes.
The merged PDF produced by Pdf24 Creator has the notes but no bookmarks.
If I do the same and checking « create bookmarks », then the merged PDF has 2 bookmarks : one for each sub-pdf. But the existing bookmarks are lost anyway.
