Happy New Years! I am starting to get familiar with Reitit (Frontend-Easy) and I'm wondering if theres something I am missing to set up a single page app router component? It appears like the route changes, the fragment gets added to url, but it doesnt seem to update the Rum/React component (unless I manually hard refresh the page-- in which case I assume something is reading the slug in the beginning?)
