I know of several groups who had no problems with Roll20 starting to have the WebRTC becoming unusable last week. All in Germany, if that helps. It is not a browser issue, as it worked (mostly) perfectly fine only a week before that. Lots of Roll20 veterans who have been using it for years, so not an user issue. We are guessing it is due to an increased demand right now, which is understandable. We are hoping for some kind of fix. Playing RPG with our isolated / quarantined friends is a very welcome escape from a bleak reality right now.
