On my iPad, the last two days, in the total product view only remains on "newest to oldest"

On my iPad, the last two days, in the total product view – remains on “newest to oldest” – will not change to any other view.  This has never happened before.  It is fine on my desktop but I do rely on the iPad to also be able to do this type of query. Anyone else experiencing this?

Are you referring to the sort order in the back end?
