Video chats need work. If you leave the meeting and try to call your friend again, it will tell you to end the other meeting. Problem: there is no where to find your current meetings!! So you can't end it. Additionally, every time you video chat a contact, they don't ever hear the call, and the same goes for me. You have to be looking at the app to see someone's calling you. And when you do finally pick up there's a chance it'll tell you it's an invalid meeting room ID. Really annoying.
