No way to Add New Pages in Pages 5.2
I'm running Pages 5.2 on a MacBook Pro (2015)
I can't figure out how to add a page to my existing document.
The instructions in the Apple "Help" section only relate to the latest version, which appears to have an "+ page" button in the menu. I understand from my research, that there're different approaches based on it being a "word-processing" or "page layout" document file. This is still not helpful since there doesn't appear to be any indication which I'm working in. I'm trying to create a multi-page catalog with text and images, so... maybe a Page-layout file? And in any event, I would welcome both paths of instruction. I've tried at least one of the suggested methods with still no resolution. I shouldn't think it's should be this difficult, but...
I appreciate the community's help on this one. If you've had experience adding pages in Pages 5.2, please respond with some detailed instruction. Thanks so much.
