Between each subsequent page load within the dashboard, the left hand menu disappears and is then re-rendered. The dashboard menu disappears like this:
A second later (which feels like ten years in UX time) the menu finally comes back. Congratulations, you've got the same menu back you already had, even if you click the very same page you're already on.
The inefficiency is infuriating and the user experience is awful. If you're clicking to a section within the same menu, the menu doesn't need to be touched.
