I am working on a Macbook Pro 16" 2019 with two external dell monitors, along with J5 create dock. I am accustomed to 3 displays and now only have two. I have gone through all of the recommendations including switching my HDMI ports to ensure it wasnt one of the ports also switched out HDMI for VGA to ensure it wasn't the cords....no luck. I am so disappointed. I have unplugged, replugged, restarted in different sequences as well. When I be better off switching back to catalina? if so how do I do that?
