PDF Portfolio file made with Acrobat 11can't be edited in Acrobat DC
We have created with Acrobat 11 pdf portfolio files. They include 4 seperate pdf files, shows the cober pages in the portfolio and on the main portfolio page we have a logo - featuring our corporate design.
Now the logo needs to be changed on the portfolio main page. It's like a header line with the logo.
But now we have Acrobat DC and I don't find the menues for editing portfolio header.
I read in some forums that maybe the Acrobat 11 had more options round about portfolios like the DC.
Is that true? Are with the latest DC version the function for editing portfolios reduced?
Or is there a hidden menue where I can get the functions.
