Is goggles still solving sudokus?view story

http://android.stackexchange.com – Some time ago I tried to solve sudokus using goggles and it worked. But today I've been recognizing several sudokus, and goggles says "it's a sudoku" and performs a google search for me, but I don't have the solving feature anymore. Is it a matter of versions? Do I have to adjust any setting? Thanks, (note: I tried to create the tag "goggles" but I don't have enough reputation) (HowTos)
