Hi Vincent, Please carefully work through to the first three steps of our guide to Solving Technical Issues: Step 1: Make sure to use the right browser - Please check if these issues persist when using both Chrome and Firefox. Step 2: Ensure that there are no extensions/addons interfering with Roll20 - Please disable all add-ons/extensions. Step 3: Clear your cache Additionally, please refer to our Video and Voice Chat wiki as you are experiencing issues with video. If the above steps do not resolve your issue, please provide us with the information listed in Step 4.and include a WebRTC Debug Log as well if possible. (Click the "Download WebRTC Debug Log" button under the Video + Audio Chat Options of the My Settings tab) If you don't see this button, then you either are using the now deprecated Legacy Roll20 WebRTC version or WebRTC is turned off entirely.
