Two problems from what I've seen so far: 1. Browser navigation overlapping website viewport in iOS Safari. What is the real height of the viewport? 2. Floating side panel on macOS: necessitates needless extension the app body. Also, the App close button is in the side panel, which is floating IN the app body. This seems like a betrayal of their so called structure philosophy.
