I want to upload a WebGL build to Unity Play,
but even the simplest build (a default URP scene with a cube) is stuck at loading.
it works on localhost, but not Unity Play
Eg:
I’m using Unity 6 – Universal 3D template with all the basic settings for the Web Platform.
the console errors are important
(the first 2 are likely me, cos I have a pi that filters out ads and stuff)
it’ out of the box unity without any installed packages in this project, so I am not sure what to do about this errors.|
I was able to upload a working WEB build with a “Publish to Play” feature in Unity 6.1b

but if I do it manually by uploading a zip file, still doesn’t load. 
are you uploading everything?
