Please put back the previous number buttons/settings – Cool Sudoku, Jigsaw, Killer, Kakuro, Sudoku X Review

Can there be a “retro” mode to go back to the previous larger buttons? The new buttons are super unpleasant to deal with. I had to go find an ancient iPad2 in order to preserve any interest. This was a favorite app for many years until this very unpleasant change.
