When I click on the :Launch Campaign" link I see this message in the side bar. The browser you are using is not compatible with WebRTC, which is required for video and voice chat. If you're using an external application such as Skype or you don't want to use video chat, you can safely ignore this message. I am currently using IE 11, what browser do I need to be using in order to utilize the voice and chat functions of Roll 20? I plan to start a campaign soon and need to figure these things out so that all of the players and I can see and communicate with me. Help!
