In classic, users can open a list and when the list is too large to show all of the items at once, the user can select "More choices". This option appears not to exist in the New UX. Lists in both the Page Selector and a list dropdown cut off at a certain # of list items and users do not have the option to select "More choices", which prevents users from accessing all information. See attached images for details.
Unfortunately, this is a roadblock for our clients in transitioning into the New UX. So if anyone has any guidance we'd appreciate assistance!
