A new one.
Interactions are listed 'most recent first', so the most recent 15 (or whatever the number is) interactions will be presented on the first page. But now within each page, the interactions are presented in the opposite order. So I have most recent at the bottom of page one instead of the top. The order of presentation is now 15th down to 1st on page one, 30th down to 16th on page two, etc.
This little gem of programming is true for page three, at least. I can't say what happens on subsequent pages because when you throw your hands into the air in exasperation it makes it hard to use the keyboard.
