Hello Game Master, I am sorry to hear that you have encountered this issue with uploading music. To rule out potential issues, please carefully work through these 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. Step 3: Clear your cache If none of the above succeeds, please thoroughly work through Step 4 . (Don't forget the Campaign's name and complete Console Log!) Additionally, you can find more information in the Bring Your Own Beat Bug Thread . Once you have followed the steps above, you can post the requested information in that thread, or once we receive your response here, we will move it to that thread and ping the devs to your issue. Thank you!
