What happened?

My game downloads but gets stuck for 25 seconds at 90%. I looked at what was going on during that time, and the browser is downloading the wasm file twice. On a chromebook with limited resources, it doesn't get cached (ever), so this doubles the download time. On a PC, everything is fine because the wasm file is cached after the first download, and the 2nd download is near instant. Is there a way to prevent it being downloaded twice? It happens somewhere in useUnityContext() before it sets isLoaded to true.

Reproducible test case

No response

Would you be interested in contributing a fix?

would it be able for you to share some code? it might be caused by unintentional rerenders

i also got the same issue on my PC chrome and mobile chrome. the *.wasm file will download twice.

I looked into rerenders, I'm new to react so I figured that could be the case, but rerendering wasn't the problem. Unfortunately many schools have extremely slow wifi, so I was forced to drop Unity for just plain JS, which is about 1/20th the size for my game. Even downloading a Unity game once is way too slow, and Chrome won't cache it on limited devices. What's the best way to get you my code in case it can help someone else? Thanks, Mark
