Since replacing my 2x Dell 27" displays with 2x Apple Studio 27" displays a few weeks ago, Acrobat 'CMD 0' (Zoom to Page Level / Fit Page in Window) no longer works.

If I use 'CMD 0' or set PDF viewing settings or document properties to Fit Page or Fit Height, the page is displayed larger than the window. This means if I then press the page down button on my keyboard, the page just scrolls up a bit to show the bottom of the current page. I have to press 'CMD -' to zoom out a little bit (which then shows all the page plus a little gap all around the page in the window) and then the page down button works properly.

I have updated Acrobat to the latest version and tried all the Apple Studio Display settings and advanced settings options in System Prefs.

Something is not working properly in Acrobat. InDesign and other page based apps are working correctly.

Can anyone, or Adobe, help? I will post this in the Adobe Support Community too.
