Surface Pro 4 camera issues

My surface has a camera on each side. When video chat is enabled, it defaults to the camera on the outside of the surface (photo mode) instead of the webcam camera needed. I can't find a way to change this default in the computer, browser (Chrome; up to date) or roll20 settings. Is there a button I'm missing?

Same here. Have you tried it with Edge? During the brief moment I got video to work it used the right camera. No sound though.

Actually, just trying some stuff on my lunch break I found this. If you go in to settings on Chrome and search for "camera". CLick on Content Settings and scroll down to the camera section. On mine (which is a clean, virgin install with no extensions, addons or flags enabled) the drop down was set to rear camera. I don't know if changing it to front will help as I can't test at work.
