Can't insert a page from a file into pdf
With a pdf opened in Preview, I go to Edit > Insert > Page from file... which opens the window where I can see my file is available to Open; it is a file made in Pages. I select it, click Open: selection window closes, and nothing has been inserted into the pdf.
Next I tried the drag-and-drop method (which is what I usually use): nothing happens when I release the file.
I have been having to convert the Pages files into pdf files before I can insert them into a pdf document.
Is there an option I haven't set properly, or is this a bug in the software?
