Custom Zoom not working

It might be a thing with my computer, but the zoom in Dorico is set to 200%. I tried Ctrl+ “-”, tried changing it in the preferences and in the “view” tab but it won’t budge. It’s really inconvenient because it won’t fit on my screen and I can’t work with it that way. What do I do?

Have you tried Z and X (with no modifier Keys)? I believe they also work as shortcuts for zoom…

Is there not a pull-down at the bottom right of the window?
