WebGL Loading Bar / Splash Screen is gone

Hello, I'm having a really strange issue. Game works fine both localhost and host server. However, **I cannot see loading bar at the start**, not even splash bar. The game starts black screen and waits you a bit until its loaded. I don't want to players thought game is unplayable since it start as black screen. How can I bring back loading screen for the WebGL? Standalone and Android versions are shown the splash screen, the problem is only occurs on WebGL. (Unity version is 2020.2.1f1)
