I've upgraded & most things are working well but I cannot find a way to adjust the picture-in-picture zoom display. I can adjust the size of the actual box itself by selecting the advanced then pressing adjust size & location button.
What I can't do is make the magnification of what is inside that box any bigger - it makes the text a tiny bit bigger, but not big enough. I seem to remember a previous OS having a scale that could be adjusted manually to allow the text within the box to be enlarged. Anyone know how to do this on Big Sur?
while i only just got a computer that i can use big sur with so i have limited experience if its not in the settings it might not be possible. https://support.apple.com/guide/mac-help/use-accessibility-features-mh35884/mac. thats a link to the apple guide on accessibility features in big sur.
A lot of times apple just randomly takes out features people like if people complain sometimes they put it back but usually not. with apple its their way or no way.
