Issue with Linked Text Boxes in Pages template

I am using the "Photo Card Vertical" template. Instead of a photo card, I want to make a 4-page (when folded) "brochure" containing the table of contents of a book. So of course I remove the photo card elements (graphics).

I have some text I want to put into a set a text boxes. The text is too much to fit in a single box, such as the one provided in the template.

I am familiar with the concept of linked text boxes, and when I paste The text into the first box, I do see the + at the bottom of the text box, meaning there is more text than can fit.

When you click this + in a document with linked text boxes, the cursor is supposed to change into a different kind, indicating that the remainder of the text can be "poured" into the next text box. However, I do not see that special cursor when I click on the +.

As a workaround, I can just create four text boxes and then just paste as much text as will fit in each box, but it would be a bit easier using linked text boxes.
