Using AWS Amplify Vue with routing

Router.vue

const router = new Router({
  routes: [
    {
      path: '/',
      name: 'Home',
      component: Home,
      meta: { requiresAuth: true}
    },
    {
      path: '/notes',
      name: 'Notes',
      component: Notes,
      params: {
        'foo': 'bar'
      },
      meta: { requiresAuth: true}
    },
    {
      path: '/menu',
      name: 'Menu',
      component: Menu,
      meta: { requiresAuth: true}
    },
    {
      path: '/profile',
      name: 'Profile',
      component: Profile,
      meta: { requiresAuth: true}
    },
    {
      path: '/auth',
      name: 'Authenticator',
      component: components.Authenticator
    }
  ]
});

router.beforeResolve((to, from, next) => {
  if (to.matched.some(record => record.meta.requiresAuth)) {
    let user;
    Vue.prototype.$Amplify.Auth.currentAuthenticatedUser().then(data => {
      if (data && data.signInUserSession) {
        user = data;
      }
      next()
    }).catch((e) => {
      next({
        path: '/auth',
        query: {
          redirect: to.fullPath,
        }
      });
    });
  }
  next()
})

Damn, don't I feel stupid now?.. Here's the link that I was looking at. I guess it's a full copy of the previous Docs version and it looked so real that I didn't even check the url...
Anyway, I guess problem solved, however, there are two things I'm struggling with:

1. With the new Amplify library changes for Vue, how can I still use it as a plugin, I mean, the portion with Vue.use(AmplifyPlugin, AmplifyModules), what do I replace that with? And should I use Hub to replace the AmplifyEventBus?
2. When using the Datastore with @auth, how can I make sure that a new logged in user will not see the records already synced to the IndexDB from the previously logged in user? Shouldn't Datastore know somehow either clear the IndexDB store or only fetch and display the records for the new user?
   Thanks a lot !
