Acrobat Standard 2017 - Rotating single pages rotates text but not page dimensions!

Hi,

I recently upgraded from Acrobat XI Standard to Acrobat Standard 2017 and, of course, the visual presentation has completely changed. I'll get used to it.

What should not have changed, however, is what happens when I elect to rotate a single page within a multi-page PDF.

For instance, let's say I want to rotate page 2, clockwise 90 degrees. Currently, it is presented in portrait orientation but its text reads sideways because that's how it was typed up before someone scanned it into a PDF. I want landscape orientation for that page as its viewed in the PDF so that its text will be right side up, so you don't have to crank your neck to read it. Simple task to rotate.

With XI Standard, I clicked on the page to "highlight" it, then clicked the "rotate" icon and, voila, it is now landscape and the text is right side up. Happy, happy.

However, with Standard 2017, I click on the page to "highlight" it, then click the rotate icon, but only the text rotates. The portrait orientation of the page stays portrait! It does not rotate to landscape. What I end up with is my text chopped off on both left and right. Do you follow me?

I don't know why this would be desirable or be the default way to rotate. In any case, can someone please tell me how to make the portrait/landscape orientation rotate along with the text? I've tried searching forums but no luck.

Thank you.
