I always assumed that was intentional to save you arriving through options. I find that behaviour quite useful as I can hit anything beginning with CHE just by typing more letters.
Some people don’t like that. I don’t know why you like having to wait but if they showed Chess for CHE you could still find other apps if you kept typing.
Maybe there are also people who like the lottery of results changing the instant you click on the app you want because it adds excitement to their lives.
