Duplicate Page - "Menu item" NOT showing for Dynamic Page

@marcusjpotter , that’s really odd. ‘Duplicate’ is definitely available for dynamic pages. Here’s a screenshot. Not only is it available, but, as you can see, I’ve just used it to duplicate ‘Photos (Title)’ and created ‘Copy of Photos’.

I notice you specifically mention ‘right click’, while I used the three dots. Right click doesn’t work for me at all.
