Major bug
Recent update no longer stores rating. Highest ELO is wrong, depending where you check. Needs a graphical description of solutions! Sometimes it shows you the next 5 best moves, sometimes just one. You can analyze to try and see the move you missed, but why not display a move-by-move on the actual board? Its like learning math from a teacher who says nothing except "right" or "wrong". Frustrating!
