Page refresh required after optIn is executed to get cookies

[markabruce]

Description

I am wanting to use my own cookie consent banner in conjunction with this library.

• this.$gtag.optIn() calling works correctly, however, a full page reload or a route change is required before the events are pushed from the dataLayer and cookies are added to the cookie store.

Expected behavior

• I'm not sure what I expect, I am not sure if this behaviour is correct

Actual behavior

See above.

Environment

Run this command in the project folder and fill in their results:

npm ls vue-gtag: vue-gtag@1.16.1

Then, specify:

1. Operating system: Mac OS
2. Browser and version: Chrome - Version 89.0.4389.128 (Official Build) (x86_64)

Reproducible Demo

main.js

import Vue from 'vue';
import VueGtag from 'vue-gtag';
import App from './App.vue';
import router from './router/router';
import store from './store/store';

Vue.use(VueGtag, {
  config: { id: 'G-xxxxxxx' },
  enabled: false,
});

new Vue({
  router,
  store,
  render: (h) => h(App),
}).$mount('#app');

is there already a solution for this? would be nice if the cookies are set as soon as the optIn() is called...
