yeah unity isn't made for webgl releases really, I've already mentioned this before in the discord, unity doesn't support many features in webgl builds, especially with lighting and cameras for some reason, and overall just chugs on web. If you are using unity I would recommend keeping your platforms to Windows and Linux because anything other than those two doesn't work too well, you might have noticed I didn't include macOS and that is because it sucks for gaming and apple yells at you for running unsigned executables and not having access to said executables. 

TL:DR having a webgl release makes your game run worse and you lose many quality settings, additionally you have to use the terminal to sideload your game if you export to Mac so I prefer to keep my games only on Windows and Linux, only using web for some specific games that are simple enough for webgl.
