I own an iPhone SE1 and the automix playlist seems a little bit not very solid, the automix button on top is not fully visible, the bottom edge of it is missing, also the way that the list and the button stretch a gap when I try to scroll the list down, also the Edit Close and Done link buttons are too sketchy and poorly visible on top of the autoplay button. I think this section of the app would work better with a row of well contrasting square with memorable symbols buttons in a row on top and on the bottom of the list.
