Sorry Alan, I did mean WP dashboard, not Elementor!
Under testimonials in that dashboard there are the following sub-heads: all testimonials, add new, categories, views. fields, settings and about. I have read through all of these sub-sections and cannot find anything that would allow me to follow your guidance to ” go to testimonials, view, select the view that you want to change, mode, display, order, newest first”
I have gone through the ‘adding reviews’ module another time to make sure I haven’t missed anything. So am now stumped! Any advice?
