Hi,
I tried to open a pdf in Affinity Photo as well as in Affinity Designer and firstly I couldn't select that I only wanted the first page and then I received the error message that there was an error with "parsing". I hope, I translated that correctly from German (Fehler beim Parsen). What is parsing? And - I really like the Affinity products much more than the Adobe products, but as long as Affinity doesn't do some things I need properly I'm stuck with the Adobe stuff as well, just for those things.
