my goodness this site is struggling hard... login page loading took many attempts (one resulting in a CF 5XX page) and not it is stuck on the confirmation....(I have no given up). Also, why is this store page fully client side rendered? the layout thrash is really noticeable. Is the store in the middle of a rewrite or something?
