I've deployed a game (WebGL Build) on Netlify using GitHub and everything appears ok apart from an mp4 won't play. The mp4 resides on GitHub. The error I get in Chrome is: “…has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.” I'm assuming this is Netlify not giving permission but I would have thought they would allow downloading files from GitHub? Is there any way around this?
