So I just created a new webgl build using the latest LTS version of Unity and when I try to use the auto-size option it tell's me I don't specify the dimensions? There dimensions set inside unity for the build so not sure why this isn't working? Any ideas?
Also when I use the click to launch in full screen the game screen that first loads doesn't show the entire game until I manually click full screen?
Edit: I just tried to also manually set the viewport dimensions to fit what I built my game in and the game doesn't show fully still unless I click full screen?
