As typical fashion, to me it feels redundant and gimmicky. whatever you can do with it, you can do just as well and faster with other menus and gestures. clicking it brings you to the app which you can also swipe ur home bar for without having to reach so far up. holding it opens a small menu which again ppl that are used to doing with control center or from the app itself will do faster. dynamic island esthetically is pleasing but lacking in practice
