Chrome and Firefox are the only browsers supported by Roll20 but o ne of the players in my game - a Mac user - had troubles using Safari as well. He doesn't like Chrome or Firefox, so he tried the DuckDuckGo browser and has had no trouble since. Note that several setting in Roll20 - such as dark mode within the game - are cookie-based, so blocking cookies on this site will mean that the user would need to reset those every time they log in. Robin said: Yes I am using Safari. It did not occur in Chrome. Just switched to an MacBook Air so was hoping someone else had a clue as to why this was occurring. Thanks!
