I was finally able to get this to work by (in my instance), placing a "Page 1 of 2" text element on the first page and ensuring that it was the last tab on page one. I then saved the form after completing all tabs on the first page.
I then created the tab order for page two in the normal process and added a "Page 2 of 2" text element at the bottom of page two, again, ensuring that it is the last tab item on the page. I saved the form.
I then swapped (by dragging the fields) the "Page 1 of 2" and "Page 2 of 2" text elements so that they were on the "wrong" pages. "Page 1 of 2" was placed at the bottom of the second page while "Page 2 of 2" was placed at the bottom of page one. I then edited the text element to indicate their correct locations (Page 1 of 2 became Page 2 of 2 and Page 2 of 2 became Page 1 of 2). So far, this process has worked for me on several forms that I've created recently.
