InDesign 2025 (v 20.0) on Mac OS 14.6.1

When opening presentation mode (Shift + W or View > Screen Mode > Presentation …) and going back to default/preview mode the application window resizes.
When having the app window to its full size after presentation mode it changes back to its smaller size that you can toggle by using the green plus icon on the top left (Mac Version).

When setting both window states manually to full size and toggling between the two (without effective size change) once it works afterwards the window stays in the same size when escaping presentation mode. But this does not work all the time an is a quite annoying work around.

I also got help via the support chat and tried to quit and reopen. This does not help. I reinstalled the previous version (Indesign 2024 v 19.5) and there it works fine.
