While too lazy to go through those steps, I will mention that I also can't load a game with the Warhammer Fantasy 4th edition sheet. It just sits on a black screen with "Loading..." under the roll20 logo. I'm using google chrome, adblock plus, ublock origin (youtube ads were getting past adblock), and windows defender for my AV. Here's the console log: app.roll20.net/:12 Refused to execute inline script because it violates the following Content Security Policy directive: "script-src 'self' 'unsafe-eval' https://*.googlesyndication.com https://*.doubleclick.net <a href="https://partner.googleadservices.com" rel="nofollow">https://partner.googleadservices.com</a> <a href="https://www.googletagservices.com" rel="nofollow">https://www.googletagservices.com</a> <a href="https://ssl.google-analytics.com" rel="nofollow">https://ssl.google-analytics.com</a> <a href="https://www.google-analytics.com" rel="nofollow">https://www.google-analytics.com</a> <a href="https://ajax.googleapis.com" rel="nofollow">https://ajax.googleapis.com</a> <a href="http://ajax.googleapis.com" rel="nofollow">http://ajax.googleapis.com</a> <a href="https://d3clqjduf2gvxg.cloudfront.net" rel="nofollow">https://d3clqjduf2gvxg.cloudfront.net</a> <a href="https://cdn.firebase.com" rel="nofollow">https://cdn.firebase.com</a> https://*.firebaseio.com https://*.tokbox.com https://*.opentok.com <a href="http://static.opentok.com" rel="nofollow">http://static.opentok.com</a> <a href="http://www.google-analytics.com" rel="nofollow">http://www.google-analytics.com</a> <a href="http://cdn.crowdin.com" rel="nofollow">http://cdn.crowdin.com</a> <a href="https://crowdin.com" rel="nofollow">https://crowdin.com</a> <a href="http://stun.l.google.com" rel="nofollow">http://stun.l.google.com</a>".
