Is goggles still solving sudokus? 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,
Yes, it does. After scanning the Sudoku it should present you with multiple results, one recognized as a Sudoku puzzle, one recognized as an object, and one recognized as text. You'll want to select the Sudoku puzzle result and then select 'Solve' on the next screen that comes up.

This was just verified on v1.9.4
