I opened my PDF in Acrobat, went to properties, and set it to "two-page (cover up)", and then saved. Then I opened the PDF in Preview (MacOS), but it still shows it as one page throughout the document.
I need it to open as a cover followed by two-page spreads (it’s a book) so that I can share the PDF with customers.
If I switch it to two-page view in Preview it looks right. If I save and reopen it looks right. But if I then share it without another user it reverts back to single pages.
If you set the initial view settings (File> Properties> Initial view), you have done all you can do. This will work in Acrobat & Reader when the user's Acrobat page display preference is set to the default "Automatic". There are three Acrobat user preferences that will override the pdf initial view settings;
Using a setting other than Automatic. (Page Display)
Accessibility settings. (Accessibility)
Restore last view settings when opening. (Documents)
