Hi All I had a really nice version of the GoKart minigame (using 2019.4.f1) working after I had gone through all of the tutorials. When it came to uploading to Unity to share, the game built and uploaded fine but a problem was that after pressing play you are stuck on the same screen with no ability to do anything (the game works fine in the editor). I read somewhere that there wasn't full support for WebGL or something in web browser(?). Assuming I needed to update WebGL and all older Packages I spent a good chunk of the day updating Packages to the latest version. This resulted in a good couple of hundred errors(!) and a non useable game. I've also tried updating to the Beta version (using 2020.01.b16) to no avail. Other than uninstalling and starting all over again, any ideas?
