I’ve deployed a new version of our HTML game extraction service that should work for GZIP compressed Unity 2020 projects. I also pushed some fixes to make decompression for older Unity games go faster by taking advantage of browser decompression instead of the fallback javascript one.
Note that I’m still resolving some issues with our CDN configuration for brotli compression, but that should be fixed in the near future. Brotli appears to be the default so you’ll have to update the “Player settings” dialog to specify gzip directly.
Due to how caching works in our system, to take advantage of this update you will have to delete your build and reupload it.
