Full screen is not filling the screen anymore. The presentation looks like a window but is in fact in full screen mode (the two arrows in the lower right corner point inwards). Not sure if this is since I run the beta of macOS. It worked fine a week or two before when I still was on Catalina.
Anyone encountering the same problem? Is there a way to fix this? My current workaround is to show the presentation in a browser and switch that to full screen.
