Issue with UI – Cryptograms - Word Puzzles for Brain Training Review

Long story short this is an Enigma type game. However. Let’s say I want to change the letter K (original letter being K) to T and then change K to O instead. I have to go and click Undo and then select either K or T (I don’t remember which and that’s part of the issue) and click it to undo my change. It’s clunky and weird and not like any enigma game I’ve played before. A shame as I enjoy the logic puzzle game app by this same app author, and that is a game I recommend.
