Enlarge screen toggle not working
I use a medical platform for my work, Semble, and there is a toggle to enlarge the patient screen, however it doesn't work. Like Zoom, where you can enlarge/minimize view. It works fine for my colleagues.
I have contacted the tech support at work and they can't help - is this possibly an Apple setting I need to look into?
Any help much appreciated. MTIA
