I have been popping in and out of the beta during the day - in between sifting compost!
I fear the scroll will win over the page - this is for the so-called "smart" phone users, and is spreading over more and more sites. Don't forget Ancestry want people to have "fun" ! - which presumably includes aimlessly flicking through a listing.
It is a serious drawback for those of us who keep a spreadsheet and want to slot new matches into order on those sheets, and generally to navigate around. In addition, pages allow you to calculate how many matches you have - I can't see anywhere to work that out now (although to be honest why do I want to know?).
I wonder how Common Ancestors work? - some of my closest matches have minimal trees of a few generations, yet the correct ancestor is being identified. They MUST be using private trees of other users.
I have found a couple of decent - and correct - matches, crossing over 2 or 3 missing generations.
BUT also some absolute howlers !!! All part of the "fun".
