Describe the bug

When I update a model record locally in the app and then I reload(in development) or close and open the app(in release) the app, the datastore returns an older version of the record and then updates to the latest version.

Expected behavior

The expected behavior is that when I reload the app or open it from a closed state the record version I should receive immediately should be at least the same version that I had before I did the reload/closed the app since the records are persisted.

Reproduction steps

1. Initialize a new amplify with default datastore project following the guide
2. paste the following in your App.tsx:

import '@azure/core-asynciterator-polyfill';
import {DataStore} from 'aws-amplify/datastore';
import {Button, View} from 'react-native';

import {Todo} from './src/models';
import {useEffect} from 'react';
import {Amplify} from 'aws-amplify';
import amplifyconfig from './src/amplifyconfiguration.json';
import {ConsoleLogger} from 'aws-amplify/utils';

Amplify.configure(amplifyconfig);
ConsoleLogger.LOG_LEVEL = 'WARN';

function App() {
  useEffect(() => {
    DataStore.observeQuery(Todo).subscribe(snaptshot => {
      const todo = snaptshot.items[0];
      console.log("todo's name from observe:", todo.name);
    });
  }, []);

  return (
    <View
      style={{
        flex: 1,
        backgroundColor: 'white',
        justifyContent: 'center',
        alignItems: 'center',
      }}>
      <Button
        title="create post"
        onPress={async () => {
          await DataStore.save(
            new Todo({
              name: '1',
              description: 'desc',
            }),
          );
        }}
      />
      <Button
        title="update post"
        onPress={async () => {
          let todo = (await DataStore.query(Todo))[0];
          console.log("todo's name before update:", todo.name);
          await DataStore.save(
            Todo.copyOf(todo, updated => {
              updated.name = String(Number(updated.name) + 1);
            }),
          );
          todo = (await DataStore.query(Todo))[0];
          console.log("todo's name after update:", todo.name);
        }}
      />
    </View>
  );
}

export default App;

3. create a record by pressing create record
4. update the record
5. reload the app
6. notice how the observeQuery first returns an old todo name and then correct todo name

Check here the screen recording:

Screen.Recording.2024-04-19.at.10.22.20.AM.mov

Notice that every time I reload the app I get a version older but in the last one I got a way old version
