Document dimensions no longer displayed.
In Preferences, I have the "Always show document page size" box checked. The page size information is no longer displayed at all. If I uncheck the above mentioned checkbox in the preferences, the document size appears normally when the curser is hovered in the lower left area of the window.
Mac version (Windows version works correctly)

I have the same problem with exactly the same version of Acrobat Pro running on macOS Monterey v 12.6.9.
I can only see the document size by hovering over the bottom left corner of the page when "Always show document page size" is unchecked.
