How to read $router.query populated on page load from a subcomponent?

[stratboy]

Hi, I'm using Vue Router and all works fine in my app. But I've got a question. If I try to read $router.query from a component, event on mounted() or created(), I get an empty object, event if I load the page from an url like this: http://localhost:3000/agritour/aziende-agricole/#/?features=biologico. Why?
It seems the only way I have to get the query is through a watcher:

      this.$watch(
        () => this.$route, function(this_route, prev_route){
          console.log('query', this.$route.query); // now it works
        },
        {
          flush: 'post'
        }
      );

But I guess this should not be the first choice.

Any idea? By the way, as you can see I'm currently using vue's option api, not composition.
