Are you using the Roll20 WebRTC or Legacy? If you're using legacy, I'd suggest switching to WebRTC (that's assuming that you're the GM, if you're not you'll need to ask the GM to switch it). What happens when you switch the player video/avatar location? "Top" popped up for me when I was in Legacy mode, but my avatar was still at the bottom. The old video/voice didn't have the option of moving the player avatars, so that may have something to do with it. If none of that works, I'd suggest following the steps outlined here . If those don't work, there is more troubleshooting help here . Post back in this thread with the info and your console log and I'm sure a dev will be along to help. :)
