User data download times

[insertokname]

I considered opening an issue for this but a "question" seems more appropriate.

Whenever i access the app as a logged in user there is a 3 second loading bar stating "Downloading user data...". The ux around this is not that great honestly. I am wondering why the app isn't making use of local storage / cookies more for storing user data. There could be a fire and forget mechanism that serves stale user data from local storage while the very slow requests happen in an async manner.

From what i can gather this call to firebase init:

monkeytype/frontend/src/ts/index.ts

Lines 81 to 85 in bd34682

	voidinit(onAuthStateChanged).then(()=>{
	if(accepted!==null){
	Cookies.activateWhatsAccepted();
	}
	});

which always calls onAuthStateChanged -> loadUser -> getDataAndInit which seems to make the following requests:

Even though the requests seem to be made in parallel the real wait time is still about 3 seconds.

My question is: is there a tehnical reason i am overlooking for the loading screen existing? Could an approach with local storage + last fetched data be done?
