Vue meta not getting updates

When I visit my internal pages vue-meta will not get updated by new page values.

Code

app.js

import VueMeta from 'vue-meta'
Vue.use(VueMeta, {
    refreshOnceOnNavigation: true
})

App.vue (main component)

export default {
  metaInfo() {
    return {
      title: process.env.MIX_APP_NAME,
      titleTemplate: `%s | ${process.env.MIX_APP_NAME}`,
      meta: [
        { name: "robots", content: "index,follow" },
        {
          vmid: "description",
          name: "description",
          content:
            "..........",
        },
        // and many more....
      ],
   }
  }
}

post.vue (internal component)

export default {
  name: "singePost",
  data() {
    return {
      post: "",
    };
},
metaInfo() {
    return {
        title: this.post.name, // not receiving data
        meta: [
            {
                vmid: "description",
                name: "description",
                content: this.post.metas[0].description, // not receiving data
            },
            // others......
        ],
    }
},
mounted() {
    this.getPost();
},
methods: {
    getPost() {
        axios
        .get("/api/articles/" + this.$route.params.slug, {
          headers: {
            Authorization: localStorage.getItem("access_token"),
          },
        })
        .then((response) => {
          this.post = response.data.data;
        })
        .catch((error) => {
            //....
        });
    },
},

Any idea?

Update

By the time I published this question it was about not getting updated then after doing some researches I've and playing around with my code I've realized that my vue-meta gets updated but, late and it causes social network websites and SEO checkers not be able to retrieve my URLs correctly.

Clarify

1. Vue-meta gets update but late
2. This late update causes SEO not be presented by the time link being shared and validate.

My full meta tags code

metaInfo() {
    return {
      title: this.post.name,
      meta: [
        {
          vmid: "keyword",
          name: "keyword",
          content: this.post.metas[0].tags,
        },
        {
          vmid: "description",
          name: "description",
          content: this.post.metas[0].description,
        },
        // Open Graph / Facebook
        { vmid: "og:type", name: "og:type", content: "website" },
        {
          vmid: "og:url",
          name: "og:url",
          content: process.env.MIX_APP_URL + this.$router.currentRoute.fullPath,
        },
        {
          vmid: "og:site_name",
          name: "og:site_name",
          content: `"${process.env.MIX_APP_NAME}"`,
        },
        {
          vmid: "og:title",
          name: "og:title",
          content: this.post.name,
        },
        {
          vmid: "og:description",
          name: "og:description",
          content: this.post.metas[0].description,
        },
        {
          vmid: "og:image",
          name: "og:image",
          content: this.post.imagebig,
        },
        //   Twitter
        {
          vmid: "twitter:card",
          name: "twitter:card",
          content: "summary",
        },

        {
          vmid: "twitter:author",
          name: "twitter:author",
          content: "@xxxxxx",
        },
        {
          vmid: "twitter:site",
          name: "twitter:site",
          content: "@xxxxxx",
        },
        {
          vmid: "twitter:creator",
          name: "twitter:creator",
          content: "@xxxxxx",
        },
        {
          vmid: "twitter:url",
          name: "twitter:url",
          content: process.env.MIX_APP_URL + this.$router.currentRoute.fullPath,
        },
        {
          vmid: "twitter:title",
          name: "twitter:title",
          content: this.post.name,
        },
        {
          vmid: "twitter:description",
          name: "twitter:description",
          content: this.post.metas[0].description,
        },
        {
          vmid: "twitter:image",
          name: "twitter:image",
          content: this.post.imagebig,
        },
      ],
    };
},

Extra

1. Recently I've read an article that because vue-meta (Vue in general) loads based on JavaScript Social media crawlers will not cache them therefore it's impossible to see my link details when I share them in FB or Twitter etc.

2. The suggested solution there was to use Nuxt and return meta data server side.

Questions

1. I'm not sure how much #1 above is correct but its a possibility
2. My app in general doesn't use Nuxt but I just installed npm package of it so it might be worth to try (as I mentioned I never used Nuxt so if that's the case of your helping solution I would be appreciate if you include a bit extra details into your answers about that).
