The Zoom function in Adobe Acrobat Pro 2023 has been found.

When first introduced to the latest Adobe Acrobat Pro earlier this month, I could not find the zoom function.  Today, I found the zoom function near the bottom of a narrow sidebar on the righthand side of documents in process.  This also contains the page number the user is on and a way to skip to a different page,  the rotate function, and various tools for zooming.  This is a great relief.  (These tools used to appear at the top of documents in process).
