MacBook Pro 14 reverts to 13" display resolution in Full Screen

Upon entering full screen on the MBP14 (2021), the available screen real estate reduces to the area equivalent to a MBP13. This cuts off the notch (as expected) and adds bezels to the sides.

It seems that Acrobat needs an update to recognize the full screen resolution of the new Macbook Pros.

This is similar to my experience with Lightroom, as posted in this thread: https://community.adobe.com/t5/lightroom-classic-discussions/lr-on-new-14-quot-macbook-pro-not-using-all-screen-real-estate/m-p/12629337
