They royals don't step into each other's events, except on occasions when the goals of their patronages overlap. Besides, since H & M are no longer working members of the royal family why would anyone expect the senior royals to attend one of their events? Susan is right that neither Sussex would want any of the royals there, in large part to the shift in seniority where the Sussexes would be lower in rank than TRMs or the Waleses.
