Another anti-pattern this UI and most modern UI has is a dramatic reduction in the number of visual cues that identify interactivity. This is a system widget, and blue indicates interactivity... but that's almost it. The shape is often used for other purposes, such as for a breadcrumb, and actually the positioning makes it look more like a breadcrumb. Furthermore, it's going to be used from a website, and thus you can't rely on the fact that the rest of the site's colors will be consistent with this particular shade of blue on an icon indicating interactivity.

It's all rather minimalist - and if a user catches it, that's fine, but if they don't, there aren't any fallbacks or additional hints as to what to do. Additionally, the icon seems fairly small from the screenshot - though on an actual device that may not be an issue. It may be too small to function as a good UX element.
