If by "clear cut logic" you mean a consistent process, then sure. But if you mean intuitive, I must disagree.

Especially because it was working fine and understandable in older iOS versions.

Also for some reason autocorrect seems to have gotten a lot worse. It has become nearly impossible to type a grocery list without all kinds of annoying wrong corrections.

Yeah, good point. Your guess was right, I meant it in the sense of consistency, not in the sense of it being intuitive without knowing about it
