Austin, sorry to hear you are having trouble with Dynamic Lighting Settings. This is not normal and we're not hearing a lot of reports on it, so I'm going to recommend that you carefully work through 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 and anti-virus programs. Step 3: Clear your cache If none of the above succeeds, please thoroughly work through Step 4 . (Don't forget the complete Console Log!)
