RealmProvider fallback taking too much time to load

How frequently does the bug occur?

Unexpectedly on Production for 5% of users

Description

Hi

I’m using @realm/react with flexible sync. My problem is after I login the app is stuck on the spinner from the fallback prop of the RealmProvider. However if I close and open the app again it still showing the loader till 8-10 minutes in some case, also this is not happening to all user it only happening to 5% of user, and occurrence pattern is unrecognizable.

Here is my code:

import React from 'react';
import {AppProvider, UserProvider, createRealmContext} from '@realm/react';

import LoginComponent from './App/Components/Views/Login';
import DemoComponent from './App/Components/Views/Demo';
import LoadingSpinner from './App/Shared/LoadingSpinner';
import {TemplateCategorySchema} from './App/RealmModels/schema';

function App(): JSX.Element {
const realmConfig: Realm.Configuration = {
  schema: [ TemplateCategorySchema ],
};
const { RealmProvider } = createRealmContext(realmConfig);

return (
  <AppProvider id={'dynamicforms-qa-jqtpx'}>
      <UserProvider fallback={LoginComponent}>
        <RealmProvider
          sync={{
            flexible: true,
          }}
          fallback={() => <LoadingSpinner />}>
          <DemoComponent />
        </RealmProvider>
      </UserProvider>
    </AppProvider>
)
}
export default App;

For some users spinner stays for minutes even if user close and reopen app issue persist for some time.

Please recommend what I'm missing here, also it is very helpful if you have any idea of the root cause.

It looks like you are waiting for the download to complete. You might find one of our examples useful to avoid the spinner: https://github.com/realm/realm-js/blob/main/examples/rn-todo-list/frontend/app/AppSync.tsx#L62-L77
