Problem opening a Multipage PDF

When I open a multipage PDF doc I can only see slide 1 how can I see the other ones

Google pdf editor free . LibreOffice isn’t a really good PDF editor, don’t use it for something it isn’t intended for.

Thanks, just want to read the PDF doc not edit it.

In that case, get a dedicated PDF reader.

Go to View, tick page pane this will show other pages in left hand side panel
