I am using the free basic account for Zoom but have a facilitator that has the premium version. We have tried the captions. I am frustrated by what I see and maybe I and the premium holder are missing something. For my captions what I see is a large white rectangular box. Inside that box is a light dark rectangular box and inside that are the letters (captions) in black. It is very hard to read. Solutions? I see nothing in Zoom help.
