I've just started using the Amazon Prime Video app on Apple TV 4k. It's web-based and frankly horrible. And not just horrible because of the technical constraints imposed by having to target a web runtime - there are some serious, glaring beginner type UI anti-patterns in the UI. Is this experience indicative of what I can expect with an Amazon TV device? (I suspect so.)
