Can’t change mistyped numbers – Sudoku Master Edition: Logic Review

There is no redo or erase function if you accidentally touched an unwanted number. You just have to stick with it. Or the function exists but is buried so deep that I looked for 5 minutes and still couldn’t find it. Can’t believe such a trashy design actually made it to the app of the day. This casts doubts on apple’s editors.
